This morning I've started experiencing a frustrating graphical issue when using Picom with the glx back end.
Here's an Imgur link with some pictures.
The entire screen goes black aside from one horizontal bar spanning the full width of the screen. It always happens in firefox but doesn't seem to happen with other applications. It most often happens when typing something into a search bar or URL bar. Youtube videos / previews also seem to trigger it.
The computer does not lock up. Moving the mouse fixes it. It flickers on and off as I continue to type.
I suspected Picom might be to blame so I disabled Picom and the issue went away. Swapping from glx back end to xrender seems to also stop the issue. I'd like to know why this is happening, though. I tried enabling each of my individual Picom settings one-by-one but no specific setting seemed to make a difference. Only the glx back end setting mattered.

[ 1568.816080] ---[ end trace 0000000000000000 ]---There are a bunch just like this. They show up after I've triggered the graphical issue.
My Xorg log is full of these lines:
[ 1565.134] (WW) modeset(0): Present-flip: queue async flip during flip on CRTC 0 failed: Invalid argumentMy dwm log has this:
(process:8775): GLib-CRITICAL **: 17:59:54.234: g_string_insert_len: assertion 'len == 0 || val != NULL' failedStuff I've tried:
As stated, disabling Picom makes the issue go away, as does switching to the xrender back end.
I'm on an up to date kernel: 6.8.4-arch1-1.
I've tried downgrading to the past few 6.8 kernel releases from my cache. I tried each one until I got to 6.7 and still had the problem. I also tried the latest LTS kernel and still had the problem.
I've googled the warning from dmesg and I can find issues that are kind of similar but they're all from multiple years ago and none of them match my issue exactly and I could not find a fix or solution.
Obviously I can just disable Picom for the time being or deal with the xrender back end but I'm curious what could have caused this issue to pop up for me since nothing about my setup has really changed over the past few days. I'd also like to report this as a bug somewhere, assuming it's not something I've screwed up somehow, but I'm not sure if this would fall on Picom or on the Intel i915 CPU driver or my WM or something else entirely.
Any help or links to more information would be greatly appreciated.
