Animation and cursor are laggy/jitter on Intel Core Ultra 7 155U

My symptoms are pretty similar to ones from this topic but happens on integrated Intel GPU.

Seems like there is something that slow down whole rendering time to time. Even if I just move the cursor it takes few seconds until it starts being delayed and jitter.

I run few commands to collect more info.

$ glxgears -info | grep GL_RENDERER
it is noticeable how gears stutter occasionally

Help to figure this out, please.

I’m thinking this env might affect that:

CLUTTER_PAINT=disable-dynamic-max-render-time

I force it globally:

sudo -e '/etc/profile.d/99-tweaks.sh'

# Clutter
export CLUTTER_PAINT='disable-dynamic-max-render-time'
3

unforunately, it didnt help. gears still stutter, and cursor too

4

What about after forcing max CPU?

sudo x86_energy_perf_policy --all 'performance' --turbo-enable '1' --force
5

tried, with the same result :frowning:

6

How much RAM have you assigned to IGPU in the bios?

7

I didn’t found any related options in my BIOS menu.

Btw, on KDE (Neon, didn’t tried Fedora spin) I have very smooth experience. Gears, desktop switching, overview, cursor - no stuttering. Latest beta Ubuntu on GNOME also feels smoother than Fedora.

Not sure whether it is helpful info in this context though

8

Does the FPS reported from glxgears go lower when it visually runs slower? Could be something like PSR affecting the display output but not the rendering?

9

yeah, FPS drops are significant. take a look at the gif

I’d run this in a separate terminal:

sudo intel_gpu_top

Then non-vsync glxgears:

vblank_mode=0 glxgears

And see how GPU load and power go.

For me it stays above 7K FPS and 1000MHz frequencies 99% load.

Xe can also use a different driver if I heard right (not too familiar how to switch but likely a GRUB/boot option?)

11

so i just tried a bare Arch with sudo pacman -S gnome and it works smooth as butter. thus, going from the opposite, i realized that the pile of trash called fedora is better to be avoided unless you’re probably amd user or like poking a stick into your eyes :slight_smile:

12

it is probably about gnome 48 using triple buffering. even my gnome 47 on my amd gpu on fedora system is laggy on animations. just a bit patience for glory

13

It’s hilarious how fedora devs sitting on laptops with intel gpu and seeing what a laggodrom they’ve assembled in this distrio, still push it to release and tolerate the fact that it is broken out of the box - something makes rendering as slideshow on their flagship workstation

14

I’ve had Intel UHD 630 for years and today F42 GNOME 48 Xorg and Wayland and it generally works well, but I’ve also disabled GNOME animations for years (I’m not convinced it can be non-laggy and I seen it AMD and NVIDIA):

gsettings set 'org.gnome.desktop.interface' 'enable-animations' 'false'
15

after disabeling animations, i felt that animations are most of the time time consuming, not more than that. when you spend time with no animations, it is becoming normal.
