--- Comment #5 from Jo <jo.y.v...@gmail.com> --- I tried to adjust performance again - without results. If I go under: preferences-display: I see: canvas graphics acceleration, renderer, scaling mode, use texture buffers : all grayed out (I'm unable to change settings) Disable vsync is checked, but also grayed out. -- You are receiving this mail because: You are watching all bug changes.
