--- Comment #43 from wg9rffujwz8y2...@airmail.cc --- For me it happens randomly (but often) when I have wine and virt-manager windows open. The wine window continues playing sound but doesn't respond to input. Since the start of this bug report I've changed GPU brand, drivers, distribution, KDE version but it was always present. But after changing "Keep window thumbnails" to "Always" as suggested here it became way less problematic. XWayland Firefox doesn't glitch for me anymore while using it, although I'll assume a startup bug I have is unrelated (say 1 every 50 times I open Firefox it opens as a small unclickable/unfocusable window). -- You are receiving this mail because: You are watching all bug changes.
