--- Comment #5 from Nate Graham <n...@kde.org> --- And with https://invent.kde.org/plasma/kwin/-/merge_requests/4207 applied, the manifestation is different again: now I get back to the original issue of mouse lag when moving over delegated of plasma popups. It appears to be the background Contrast effect that causes this problem; if I turn it off, the problem goes away. And if I have it on--even with the Blur effect off--the problem remains. -- You are receiving this mail because: You are watching all bug changes.
