--- Comment #1 from Antonio Orefice <kokok...@gmail.com> --- Ok, i've to add several information to this report, sorry. The slowness was due to a setting i have in my kwinrc: MaxFPS=300 I have to specify it because: 1) with vsync disabled, kwin render frames at 60hz, why? i don't know. 2) i switch between 60hz and 75hz and 300 is the closer multiple integer to both. -- You are receiving this mail because: You are watching all bug changes.
