Zoom flatpak app flashes rapidly, (wayland, gnome, nvidia, fedora 40)

Hi, I have recently encountered an issue with the zoom flatpak app. When using the wayland, the app rapidly flashes - making it near impossible to use. I want to use wayland to be future proof, and the zoom browser app is not powerful enough. Is there any way I could fix this?

Can you try the zoom rpm version?

If that also fails to work we will need details of your system to suggest a reason.

What is the output og inxi -FGxx (post as preformatted text using the </> button)?

RPM Version has the same issue, forgot to say I had an nvidia GTX 1080.

I have just tested the Zoom RPM on my system and that worked. But I have AMDGPU not Nvidia.

If you have the rpmfusion NVidia drivers then you have the best drivers installed.
But I wonder if the problem is the lack of explicit sync in nvidia drivers?
See this blog that explains why explicit sync is important, especially for nvidia drivers: Explicit sync | Xaver’s blog

FYI my settings:

I read the article, looks like that’s the cause of the problem.
Is there any workaround for this issue, or will I have to switch to xorg until Explicit sync is implemented into xwayland?

I use zoom (rpm version) with the X11 DE. It works well.
What I do when attending a zoom meeting is verify that I am logged in with X11. I have a couple other apps that also have problems with wayland so I often remain in the X11 DE.

So far I have not been impacted with changes between wayland and X11 other than a (very) few apps that do not work properly with wayland. (Steam, Chrome, and Zoom among them)

I have an nvidia RTX 3050 GPU.

We have to be careful to distinguish apps that have a Wayland compatibility issue on any GPU and the apps that have an issue on a specific GPU.

nvidia’s lack of implicit sync seems to be at the root of a lot of compatibility issues.

For example I have no issues with zoom or steam on amdgpu with Wayland.
I do not use Chrome so cannot comment on its compatibility issue.

Added nvidia

By “logged in”, you mean the zoom app or the whole KDE? Some of my apps may need X11 too…

10

Log in to the whole DE choosing X11.
