--- Comment #2 from Thomas Lübking <thomas.luebk...@gmail.com> --- wild guess: no subpost, thus EGL_BUFFER_PRESERVED, thus no flipping, thus tearing (cause the swap isn't fast enough for the vblank time) if you enable kwin debug output and start it from konsole, you should get a line like "EGL implementation and surface support eglPostSubBufferNV, let's use it" -- You are receiving this mail because: You are watching all bug changes.
