--- Comment #10 from Ilya Fedin <fedin-ilja2...@ya.ru> --- Ah, I remembered a thing: tdesktop forces Qt to compose via OpenGL by overriding QWidgetPrivate::rhiConfig since 4.8.0 as various compositors (e.g. mutter) have bad compatibility with Qt's wl_shm implementation. Maybe Plasma has performance problems with (frameless?) wl_shm windows. -- You are receiving this mail because: You are watching all bug changes.
