@vanvugt "If we could reproduce this reliably in development (...)". I tested it many times here and it is absolutely constant, regular, persistent, stable.
- Monitor's internal settings > "Auto Input Switch" = on : This bug always shows, in every conditions. - Monitor's internal settings > "Auto Input Switch" = off : This bug never shows, in every conditions. "every conditions" means: Ubuntu settings > screen power saving > screen blank -or- Ctrl+L -or- "sleep 1; xset DPMS force off" And "screen blank" = "Turn the screen off after a period..." It is written right there, in those settings.
