Bug ID: 480819 Summary: Window Glitching When Snapping to Left or Right in Wayland Classification: Plasma Product: kwin Version: unspecified Platform: Arch Linux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: k...@lew1s.com Target Milestone: --- SUMMARY I've included a video of the issue because it's easier to show than describe: https://mega.nz/file/DDZVwR7Q#YTJqguszTzMMvxyGg6d75ynU9TEgnnB5S3f36a9QdAY The issue is that occasionally when snapping windows to the left or right of the screen, there will be a visual glitch and cause all sorts of unexpected results. It tends to only happen with web browsers, and more frequently with Progressive Web Apps, as you can see with Gmail in my example video. The PWA I was demonstrating uses Chromium, but I’ve also had this occur with Chrome and Brave. The Appearance settings in the browsers are set to “classic”, but it happens with GTK and QT as well. I’ve set all themes back to default Breeze default to ensure it wasn’t a theme issue. I’ve only been able to reproduce this issue in Wayland. When running X11, it works just fine. STEPS TO REPRODUCE 1. Open PWA 2. Snap to either left or right 3. (I can't always reproduce the issue on demand, but it does happen very frequently) OBSERVED RESULT Visual distortion after window snap EXPECTED RESULT Clean snap to either left or right side of screen SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.114.0 Qt Version: 5.15.12 kwin 5.27.10-2 wayland 1.22.0-1 ADDITIONAL INFORMATION -- You are receiving this mail because: You are watching all bug changes.
