Comment 3 leodream2008 2024-10-18 10:37:17 UTC

For my DP external display, the issue happens only when the Night Light feature is on or the display's brightness drops below 100%. 
It may be a workaround.

Comment 4 Landgraf132 2024-10-18 15:48:13 UTC

The issue does not reproduce in version 6.2.1.1.
