It should be fixed by the time 5.23 releases. Does your BIOS have a primary GPU setting? If that defaults to the Matrox card that would explain the issue, KWin honors that setting. We should probably still switch to a different GPU when we detect that the primary one doesn't have hardware acceleration though. -- You are receiving this mail because: You are watching all bug changes.
