Last time I tried kdesrc-build the head-desk-banging went to a 9 on the Richter scale but I can absolutely try building just Kwin with some modifications to test some stuff. You're right that the asahi drivers don't yet support hardware cursors, and I can note that I see refreshes at 30hz in the FPS plugin when I move the mouse (that doesn't bring it any higher) -- You are receiving this mail because: You are watching all bug changes.
