--- Comment #7 from zvova7...@gmail.com --- Looks like. ksysguard in many instances work fine with shadows(normal size in shadow settings) in x11, in wayland much slower. So there is 2 problems: 1. konsole in anywhere slow with many instances because translucent is flagged in all cases and also in case when translucent and blur is disabled in konsole profile. 2. Wayland kwin backend has some problems with rendering translucent windows. But not sure, because with disabled shadows with many instances of ksysguard is also faced slow rendering -- You are receiving this mail because: You are watching all bug changes.
