CCS corruption when resizing windows
With Mesa 18.1.9, CCS corruption can be easily reproduced by resizing 2 windows at once:
- win-left to place a firefox window on the left half of the screen
- win-right to place a firefox window on the right
- drag center line left/right to resize both windows at the same time.
This reproduces with several applications, including emacs and qt apps. I couldn't get it to repro with nautilus.
Does not reproduce with:
- Driver "intel"
- Option "AccelMethod" "none"
Also reproduces with XWayland. Jason Ekstrand asked me to write this bug up here.
