Flickering XWayland programs after resume from suspend

Flickering XWayland programs after resume from suspend

[Sébastien Lerique]

Dear all,

I use SDDM and Sway, and since a couple weeks I experience a bug 
where several programs start flickering after I resume from 
suspend, to a point that they are unusable. This happens at least 
on Emacs and Firefox (I admit I haven't tested on IceCat), happens 
in both Sway and Gnome on Wayland, and does not happen in Gnome on 
X11. Which makes me think it is related to XWayland.

On Emacs, some select letters (often 'o') are not rendered. Parts 
of the windows are not refreshed when other parts are updated. 
Logging out (to SDDM) and back in fixes the issue.

Has anyone been experiencing this? I'm not sure how to start 
troubleshooting, or what channels to use to explore this. Any help 
will be much appreciated!

Best,
Sébastien

I'm using sway, and I do not have this issue.  I use Firefox and Emacs.
I've been running sway for days at a time.  At night I close the laptop
lip, and I keep computing for the next day.

I do not have this issue.

Thanks for the report. It turns out this happens also on Gnome on 
X11, and on Waybar sometimes, so it's not an XWayland issue. Here 
are two videos of some of the behaviour (this is after a full 
update of system and profile):

And here are my system and profile configs: 
https://gitlab.com/wehlutyk/guix-config (`config.scm` and 
`sl-manifest.scm`).

I thought it was a hardware issue for a moment, but logging out 
and back in fixes it. Any advice for where to start about this is 
much appreciated!

Best,
Sébastien

Thanks for including the videos!  I always think windows of bugs 
are the most helpful!

I suppose you could just exclusively use wayland applications...
Not exactly the best way to fix it.

Hi,

I've been experiencing the same set of problems (as shown on the videos)
lately and I think it might be kernel/video drivers related. It started
to manifest when I upgraded linux-libre to one of the latest versions
(5.9 -> 5.10 not sure exactly which one was it). I've resolved it by
downgrading to linux-libre-5.4.

I have Lenovo Thinkad X240 with this graphics card: 00:02.0 VGA
compatible controller: Intel Corporation Haswell-ULT Integrated Graphics
Controller (rev 0b)

Hope it helps.

Jiri

Yes, same machine and same graphics card. Makes sense, thank you 
very much for the hint!
