Conn O'Griofa <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #16 from Conn O'Griofa <[email protected]> --- In case it helps, 6.5.0 -> 6.5.1 did fix direct scanout for the moonlight-qt streaming client, but another open source application that still exhibits direct scanout issues in 6.5.1 is Firefox in native wayland mode (but xwayland mode seems to work OK). Prerequisites: * Enable showcompositing plugin in KWin * In Firefox, ensure widget.wayland.fractional-scale.enabled is set to true via about:config (normally needed for direct scanout to work if fractional scaling is set by the system), otherwise all other config is set to default. Procedure: Test1: MOZ_ENABLE_WAYLAND=0 firefox https://www.google.com -> enter fullscreen via F11 and wait for cursor to settle. Test2: MOZ_ENABLE_WAYLAND=1 firefox https://www.google.com -> enter fullscreen via F11 and wait for cursor to settle. Test3: chromium https://www.google.com -> enter fullscreen via F11 and wait for fullscreen notification to disappear. Results: Test1: direct scanout works Test2: direct scanout does not work Test3: direct scanout works (same for other chromium-based browsers such as Chrome and Brave) I believe that direct scanout was working fine in all of the above test cases in Plasma 6.4.5 (as seen in the Fedora 43 KDE live iso, for example). -- You are receiving this mail because: You are watching all bug changes.
