Bug ID: 477099 Summary: Fullscreen games tearing with a thick black bar Classification: Plasma Product: kwin Version: 5.27.9 Platform: Archlinux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: vrienddun...@gmail.com Target Milestone: --- Created attachment 163217 --> https://bugs.kde.org/attachment.cgi?id=163217&action=edit Black bar screen tear SUMMARY When "allow tearing" is enabled, a tear during fullscreen gameplay shows up as a big black bar, instead of 2 different frames being displayed by different parts of the screen. (see attachment) STEPS TO REPRODUCE 1. Display fullscreen game without V-sync 2. Let frame rate fall below monitors current refresh rate (set to 120Hz (it can do 144Hz) in my case) OBSERVED RESULT A black bar appears where I'd expect a "screen tear" (happens frequently, is annoying) EXPECTED RESULT The old frame is partially shown and the new frame is partially shown SOFTWARE/OS VERSIONS Linux: 6.6.1 KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.112.0 Qt Version: 5.15.11 ADDITIONAL INFORMATION GPU: GTX1060 6GB (proprietary NVIDIA drivers) -- You are receiving this mail because: You are watching all bug changes.
