--- Comment #9 from cwo <[email protected]> --- Showing the desktop briefly while moving between two windows in a group is a known issue - when the mouse is travelling between the two, there's a zone where the effect is cancelled (as the mouse isn't over any thumbnail). Showing the wrong window (or more precisely, turning the effect off despite hovering over something) is also a known issue when moving quickly - in some situations, the handler for the pointer leaving the first thumbnail is handled after the handler for starting the effect on the newly hovered window, so is immediately cancelled. (This is particularly easy to trigger if previews are disabled) I had a workaround/fix for these a while ago, but couldn't find someone to do a code review. I haven't tried the patch in a few months, but it seems to still apply cleanly and probably still works: https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/2816. These issues shouldn't cause a flicker while hovering over a thumbnail, and shouldn't apply to the alt-tab switcher, so these are new (or another existing bug in the task switcher case, I haven't checked) . And from a quick testing it seems I can't reproduce the alt-tab one (but I usually have the effect firmly disabled on both). -- You are receiving this mail because: You are watching all bug changes.
