--- Comment #9 from Gary Carter <kit...@gmail.com> --- (In reply to Zamundaaa from comment #7) > So there's a few things you can test to narrow this down: > 1. with the dedicated GPU set as primary, do games freeze if they're on the > laptop screen? No, everything (mostly) works fine regardless of screen with the first workaround, though I don't get a mouse cursor while over on the laptop panel in multi-monitor mode for some reason... > 2. with the integrated GPU set as primary and KWIN_DRM_NO_DIRECT_SCANOUT=1 > set, do games still freeze when they're on the external screen? This also fixes the issue! I tried swapping the card order and then not exporting KWIN_DRM_DEVICES at all, and confirmed the System Settings -> About panel went back to showing RENOIR, and I can still Alt-Tab just fine. (I did also try KWIN_DRM_DEVICES once more and re-confirmed that the bug *does* come up in that case) > 3. set QT_LOGGING_RULES="kwin_*.debug=true", trigger the bug and upload the > output of "journalctl --boot 0 --user-unit plasma-kwin_wayland" here > afterwards I'm on Artix, which uses OpenRC (so no journalctl), *but*, I believe I figured out where that logging went (~/.local/share/sddm/wayland-session.log) and attached. I can already see something that looks suspicious, though - a whole lot of this around when I triggered the bug: kwin_wayland_drm: Presentation failed! Invalid argument kwin_wayland_drm: Atomic commit failed! This should never happen! Invalid argument kwin_wayland_drm: Flags: kwin_wayland_drm: DRM_MODE_PAGE_FLIP_EVENT Let me know if there's anything else you'd like me to test; I'm more than happy to help.
