Ubuntu MATE 22.04 onwards use the Metacity theme from upstream Yaru,
which I maintain.

I have tried reproducing this issue and can only do so in one scenario:

 - In the Live Session while using the nouveau driver for NVIDIA GPUs.

@Simon Morgan: Please provide more details about your iGPU/dGPU and
drivers.

## Work around

 - Press Alt+F2
 - Run: marco --replace

Or, use MATE Tweak to set the DPI to HiDPI.

  displays

Bug description:
   HiDPI scaling is broken in Mate 1.26 produced unscaled/corrputed
  Windows buttons

  Steps to reproduce:

  Mate Tweak > Windows > HiDPI change from "auto" to "HiDPI"
  Result: A lot of flickering then everything looks fine at 200%
  Reboot & login: Window title buttons are all of a sudden unscaled again while 
the rest is as expected (see image)
  Default wallpaper is grainy at 200% // No workaround

  Workaround 1: Mate Tweak > Windows > HiDPI change from "HiDPI" to "auto" and 
back to "HiDPI"
  Workaround 2:  Change theme from Yaru Light to something else and back to 
Yaru light
