Strange rendering issue on background, around windows, the mouse, etc.

[norwegiandemon]

Fresh install of Debian 12 today.

I've tried different desktop environments (KDE, Gnome, and XFCE) but they all present the same issue. Heck, I even tried other distros for giggles and they all have the same problem.

When I used an older version of the kernel (5.10) the issue is NOT present, so I suspect it has something to do with a change with the Intel i915 driver between revisions perhaps?

This is an older laptop, under powered, but dangit I like putzing around on this thing and don't want to chuck it just yet.

Attached are printscreen (where you can't see the issue), a manual screenshot from my phone of the exact same screen that shows the issue.

That's really weird, have you tried xserver-xorg-video-intel instead of modesetting for X?
viewtopic.php?t=149472

man modesetting will tell you some options, like AccelMethod none you could try. Let people know if you have trouble. The place to do it is /etc/X11/xorg.conf.d you can probably find a forum thread here with a snippet for you. or somewhere around /usr/share/doc/xserver-xorg-video-intel

There used to be support for xrender instead of opengl in plasma, but I think that's no longer supported. Check the system settings > display and monitor > compositor and see if lowering the latency helps, or just turn off with alt-shift-F12

Good Luck,
bw

Tried the system settings first because mucking around in X11 didn't sound too appealing - however, no joy in Mudville.

I did some work on xorg and it appears I was able to force the Intel driver over modesetting

Did this by creating and then editing the xorg.conf file in /etc/X11/ so it reads like this:

Code: Select all

Section "Device"
        Identifier "Device0"
        Driver "intel"
       Option      "AccelMethod"  "uxa"
EndSection

I made sure to try no AccelMethod along with sna, or blt just to be sure, but none of those made a difference.


Again, still no luck
