Might be slightly slower, but the lags are the same. Regarding the difference between GLX and EGL, that might be the implementation in mesa, don't know. > Next test would be to deactivate all effecs in "kcmshell5 kwineffects" - or > go for the simpler way: Or even simpler: Just switch of compositing: Compositing =========== Compositing is not active It's actually a bit embarrassing that I didn't try this before. Anyway, even with compositing switched off, I see the lags, so it's safe to say that it's unrelated to compositing. > Preferred candidates: > slidingpopups > kwin4_effect_morphingpopups > kwin4_effect_fade > blur > contrast Despite the above I tried specific effects and didn't find any of them to make a difference. -- You are receiving this mail because: You are watching all bug changes.
