Wayland and Chromium/Brave GPU acceleration is suddenly broken, videos hella laggy

Ask Fedora

Fedora 42 KDE with RX 580 GPU, system up-to-date across the board as of this post.

In the last week, some update completely broke Brave’s ability to use my GPU for acceleration/compositing. chrome://gpu shows only software acceleration all the way down the list.

Videos are super laggy. This occurs in both native and flatpak installs of Brave and Chromium browsers. No combination of launch flags will fix it.

No issues in Firefox. No issues with local 4k video files or when playing games.

Switching Brave to X11 using launch flags solves the laggy playback issue and chrome://gpu again shows hardware acceleration working.

HOWEVER the entire rest of the browser becomes a laggy mess with X11… Need Wayland to be fixed.

Yea it appears something in chromium has broken. I’m having issues with Discord/Spotify freezing for a few seconds at a time. I tried a few chromium based browsers and I was also getting the same issues. I tried passing the arg –disable-gpu and that didn’t seem to help. I am running Fedora 43 beta Gnome, with an AMD 7900xt.

KDE F42, Nvidia RTX 2070 running the Nvidia drivers. Installed brave and looked at the GPU flags.

I see the following but playback seems to be utterly fine for me. What are you both seeing that gives cause for concern, other than choppy video playback?

[Enabled Toggle Names]
----------------------
*   lazy_clear_resource_on_first_use: 
    (https://crbug.com/dawn/145):
    Clears resource to zero on first usage. This initializes the resource so
    that no dirty bits from recycled memory is present in the new resource.

*   disable_indexed_draw_buffers: 
    (https://crbug.com/dawn/582):
    Disables the use of indexed draw buffer state which is unsupported on some
    platforms.

*   flush_before_client_wait_sync: 
    (https://crbug.com/dawn/633):
    Call glFlush before glClientWaitSync to work around bugs in the latter

*   disallow_spirv: 
    (https://crbug.com/1214923):
    Disallow usage of SPIR-V completely so that only WGSL is used for shader
    modules. This is useful to prevent a Chromium renderer process from
    successfully sending SPIR-V code to be compiled in the GPU process.

*   use_placeholder_fragment_in_vertex_only_pipeline: 
    (https://crbug.com/dawn/136):
    Use a placeholder empty fragment shader in vertex only render pipeline.
    This toggle must be enabled for OpenGL ES backend, the Vulkan Backend, and
    serves as a workaround by default enabled on some Metal devices with Intel
    GPU to ensure the depth result is correct.

*   timestamp_quantization: 
    (https://crbug.com/dawn/1800):
    Enable timestamp queries quantization to reduce the precision of timers
    that can be created with timestamp queries.

*   use_blit_for_buffer_to_stencil_texture_copy: 
    (https://crbug.com/dawn/1389):
    Use a blit instead of a copy command to copy buffer data to the stencil

----------------------
*   lazy_clear_resource_on_first_use: 
    (https://crbug.com/dawn/145):
    Clears resource to zero on first usage. This initializes the resource so
    that no dirty bits from recycled memory is present in the new resource.

*   use_temporary_buffer_in_texture_to_texture_copy: 
    (https://crbug.com/dawn/42):
    Split texture-to-texture copy into two copies: copy from source texture
    into a temporary buffer, and copy from the temporary buffer into the
    destination texture when copying between compressed textures that don't
    have block-aligned sizes. This workaround is enabled by default on all
    Vulkan drivers to solve an issue in the Vulkan SPEC about the
    texture-to-texture copies with compressed formats. See #1005
    (https://github.com/KhronosGroup/Vulkan-Docs/issues/1005) for more
    details.

*   vulkan_use_d32s8: 
    (https://crbug.com/dawn/286):
    Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When
    available the backend will use D32S8 (toggle to on) but setting the toggle
    to off will make it use the D24S8 format when possible.

*   vulkan_use_s8: 
    (https://crbug.com/dawn/666):
    Vulkan has a pure stencil8 format but it is not universally available.
    When this toggle is on, the backend will use S8 for the stencil8 format,
    otherwise it will fallback to D32S8 or D24S8.

*   disallow_spirv: 
    (https://crbug.com/1214923):
    Disallow usage of SPIR-V completely so that only WGSL is used for shader
    modules. This is useful to prevent a Chromium renderer process from
    successfully sending SPIR-V code to be compiled in the GPU process.

*   vulkan_use_demote_to_helper_invocation_extension: 
    (https://crbug.com/42250787):
    Sets the use of the vulkan demote to helper extension

*   use_placeholder_fragment_in_vertex_only_pipeline: 
    (https://crbug.com/dawn/136):
    Use a placeholder empty fragment shader in vertex only render pipeline.
    This toggle must be enabled for OpenGL ES backend, the Vulkan Backend, and
    serves as a workaround by default enabled on some Metal devices with Intel
    GPU to ensure the depth result is correct.

*   timestamp_quantization: 
    (https://crbug.com/dawn/1800):
    Enable timestamp queries quantization to reduce the precision of timers
    that can be created with timestamp queries.

*   use_vulkan_zero_initialize_workgroup_memory_extension: 
    (https://crbug.com/dawn/1302):
    Initialize workgroup memory with OpConstantNull on Vulkan when the Vulkan
    extension VK_KHR_zero_initialize_workgroup_memory is supported.

*   vulkan_direct_variable_access_transform_handle: 
    (https://crbug.com/387000529):
    Transform handles using direct variable access.

*   enable_integer_range_analysis_in_robustness: 
    (https://crbug.com/348701956):
    Compute the range of the index with Integer Range Analysis in the
    robustness transform and skip doing index clamping when the out of bound
    access cannot happen.

*   use_spirv_1_4: 
    (https://crbug.com/422421915):
    Use SPIR-V 1.4 if available

*   blob_cache_hash_validation:

@anothermindbomb When I use X11, my gpu report correctly lists my GPU device ID as 0x67df and driver_vendor as Mesa ACTIVE.

With Wayland, there is no GPU ID, it just says DEVICE=0xFFFF and lists the driver as SwANGLE.

Problem is, I can’t just use Brave in X11 because it gets unbelievably laggy everywhere besides video playback. Scrolling and UI delays up to three seconds.

Compare below (I cut the reports at the GL_VERSION line):

@wescode Does your about://gpu page show that everthing has fallen back to software rendering?

8

I concur - looks like you have no support for your RX 580 in Wayland.

Does a driver (AMDGPU might be the name - I’m not sure as I don’t have an AMD gpu) get loaded at all under Wayland - inxi -Gx should tell you.

9

@anothermindbomb I’m not sure what to do with that command, Terminal says “command not found.”

However, Brave in Wayland mode is the only place where graphics driver ISN’T working. My games all play just fine like always, and there are a few that are VERY sensitive to having the drivers working properly. I can also still play local 4k video files with no issues, and Firefox still plays video streams properly.

It’s just Brave and Chromium that are broken with Wayland.

10

@anothermindbomb Oh wait, got it. I’m a dunce. Output of inxi -Gx:

It appears to be only Chromium/Brave that aren’t talking to Wayland anymore.

Question now is, is it Chromium or Wayland that’s broken the connection?

11

You’ll need to install it - it just collects a load of information about you machine and makes it easy to paste in here. BIOS versions, detected hardware, drivers in use, etc.

However, if you’re seeing good framerates in graphical intensive software like games, we can be reasonably sure it’s getting a driver.

12
  • Fire up journalctl -f in a terminal to watch the end of the journal log.
  • Start up Brave
  • Play a video
  • Is anything whinging and complaining about not being happy and falling back to software rendering?
13

I’d be suspecting Chromium from posted like this

14

It does not, hardware rendering is working. I’m not entirely sure if we have the same issue. Anything that seems to be using chromium/electron lags/freezes. The apps I’ve tested so far are Discord/Spotify/Chromium. All three of those apps will occasionally freeze for 3-5 seconds, then become responsive again. I haven’t been able to figure out what the root cause is because there doesn’t appear to be anything in the logs/journal when it happens. It just started within the past week or so on F43.

15

:unamused_face:

16

This is exactly how Brave behaves when using X11 for me.

17

Just in case someone else stumbles accross this post and has the same issue I did, the fix I mentioned here: Brave browser freezing · Issue #58 · CachyOS/copr-linux-cachyos · GitHub

18

I have a similar issue. It started with Signal Desktop, after it upgraded (presumably to a new version of Electron?), now it shows up in chromium as well. It mostly looks like a screen corruption, with green stripes etc.; sometimes the entire desktop environment freezes.

I’m on an AMD A8-7600 with

For me the issues went away after downgrading to chromium-141.0.7390.54-1.fc41 with

cd /tmp/
bodhi updates download --updateid FEDORA-2025-2d4d91b00a
sudo dnf install chromium-141.0.7390.54-1.fc41.x86_64.rpm chromium-common-141.0.7390.54-1.fc41.x86_64.rpm

I meant to use chromium-141.0.7390.54-1.fc42 but looks like it’s the same.

I added a versionlock for good measure:

sudo dnf versionlock add chromium-141.0.7390.54-1.fc41
