--- Comment #3 from Robert <robert.biel...@outlook.com> --- Just following up, I can confirm that after setting the environment variable KWIN_DRM_NO_DIRECT_SCANOUT=1 and rebooting, there is no stutter present and everything is perfectly smooth in the same gaming scenario when receiving desktop notifications. This likely points to a bug in the direct scanout implementation. -- You are receiving this mail because: You are watching all bug changes.
