Are you sure that turning it on or > off is the deciding factor? You're right, the env var isn't the deciding factor. Without `KWIN_USE_OVERLAYS=0` the flashes still happen; my earlier clean period was the re-login or chance. It also doesn't look like KWin. With KWin 6.8.1, Mesa 26.2.5 and firmware unchanged: - 7.3.0-4-cachyos: flashes reproduce repeatedly when windows open, close or take focus (e.g. a loop opening/closing a Konsole window every 3 s). - 6.18.55-2-cachyos-lts: no flashes in 80+ minutes of the same kind of use. - Back on 7.3.0: flashes again. Two KWin screencasts made while I saw 3 flashes show no dark frame at those moments, so KWin's composited output looks correct. drm.debug captures (0x14 and 0x102) show only routine page flips at the flash times. I've reported it to drm/amd as a likely 7.3 display regression: https://gitlab.freedesktop.org/drm/amd/-/issues/6044 I think this can be closed as not a KWin bug. I'll reopen if it points back to KWin. -- You are receiving this mail because: You are watching all bug changes.
