Since upgrading to Fedora 35, I have encountered significant artifacting on various hardware. Here are more details:
- Login manager: lightdm or gdm
- Session manager: xfce4
- Window manager: i3
- Hardware: issue encountered on
- HP ZBook Fury 15 G7 (CometLake-H GT2 UHD Graphics + NVIDIA Quadro T2000 Mobile Max-Q), using nouveau for the NVIDIA GPU
- Lenovo Legion 7i 15IMH05 (CometLake-H GT2 UHD Graphics + NVIDIA Geforce RTX 2080 SUPER Mobile Max-Q), using the proprietary driver for the NVIDIA GPU
- Toshiba TECRA Z50-E (Intel UHD Graphics 620)
The artifacts manifest as screen tearing (always) and as “horizontal 8x1 lines” covering zones that get repainted on screen. I can try to film them if it could help debugging.
I tried using a compositor (compton or picom), but it adds noticeable input lag, especially on high refresh rate screens (the Legion 7i for example), which make it unusable.
GNOME (Wayland and Xorg) seems unaffected. Sway (Wayland equivalent of i3) seems unaffected also.
Those artifacts weren’t present on Fedora 34, so I assume something changed regarding the Intel graphics driver? If so, does anyone have pointers on this?
