repaint issues (xwayland, warhammer3-linux)
Hello,
I've spent most of my 1st christmas vacation day hunting down an repaint issue, and I think it's an libx11 bug.
I use archlinux, swaywm, wayland, steam, Xwayland for the game TotalWarWarhammer3, specifically the native linux port by feral-interactive.
Switching radv, amdvlk, linux60 or linux61 made no difference, neither did up or downgrading mesa.
After downgrading various packages (which were installed recently, via pacman.log), frustration and much coffee, I think I found the culprit:
[2022-12-16T16:31:35+0100] [ALPM] upgraded libx11 (1.8.2-2 -> 1.8.3-1)
During my quest I did do a screencapture of a repaint issue: https://youtu.be/mOvVEvnEnVI
While this illustrates repaint issues in the launcher of the game, the really annoying issue was in-game. Whenever the mouse/cursor (visible or invisible: as-in camera movement) reached the window/pane/monitor border, repainting would stutter or stop.
Downgrading to libx11 1.8.2 seems to fix every problem I had with repaints. Do you want more info? How would I provide such?
Thx
