--- Comment #12 from zvova7...@gmail.com --- I had installed gnome, run under wayland, and create 50 windows od gedit(and then gnome-terminal) - performance is ok. Then i make 50 windows of ksysguard(uses wayland mode) - faced slow rendering, with konsole same situation. So: 1. GTK applications correct informs gnome compositor about opaque surfaces. 2. KDE/Qt applications always in transclucent mode. 3. GTK applications is always in transclucent mode under kwin compisition. Maybe kwin-wayland doesn't uses opaque flag and always goes to the transclucent composition for all window? And second problem - that the Qt applications nothing inform about opaque surfaces, and compositors take default value as opaque = true. -- You are receiving this mail because: You are watching all bug changes.
