Bug ID: 391956 Summary: When in fullscreen some windows do not fill the entire screen when scaling is applied Product: kwin Version: 5.12.3 Platform: Ubuntu Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: core Assignee: kwin-bugs-n...@kde.org Reporter: carlon.l...@gmail.com Target Milestone: --- Created attachment 111457 --> https://bugs.kde.org/attachment.cgi?id=111457&action=edit Shot showing the issue. When display scale != 1 is set, some windows do not fill the entire screen. Small transparent lines appear on the border of the screen, like the window was not sufficiently large to fill the entire screen. I'm attaching an image that shows what I'm describing: I created a sample fullscreen window in QML, entirely filled with orange color. Then I bring konsole to front. On the bottom of the image there is a orange line of height equal to 1 pixel exactly. That means konsole is not large enough and the window below shines through, like there was a wrong approximation during scaling. On the left instead, there is a vertical line, of width 1 pixel, of white color. In that case the orange window below is not visible because the orange window itself was not large enough to fill. Same happens with many other windows, including other KDE apps, VLC player or even when showing the youtube player in fullscreen with chrome. -- You are receiving this mail because: You are watching all bug changes.
