Bug ID: 505895 Summary: Full screen videos in Firefox are placed incorrectly on multi-monitor setups. Classification: Plasma Product: kwin Version First 6.4.0 Reported In: Platform: Fedora RPMs OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: kwin-bugs-n...@kde.org Reporter: kdeb...@thewalkingglitch.com Target Milestone: --- Created attachment 182471 --> https://bugs.kde.org/attachment.cgi?id=182471&action=edit Monitor layout configuration. SUMMARY Full screen videos in Firefox are placed incorrectly on multi-monitor setups. STEPS TO REPRODUCE 1. Open a video with Firefox. 2. Place the Firefox window on your side monitor in vertical orientation. 3. Set the video to full screen. OBSERVED RESULT The full screen video is placed partially off the bottom of the vertical monitor. EXPECTED RESULT The video should render centered on the vertical monitor. SOFTWARE/OS VERSIONS Operating System: Fedora Linux 42 KDE Plasma Version: 6.4.0 KDE Frameworks Version: 6.15.0 Qt Version: 6.9.1 Kernel Version: 6.14.11-300.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 5800X3D 8-Core Processor Memory: 128 GiB of RAM (127.0 GiB usable) Graphics Processor: AMD Radeon RX 6900 XT ADDITIONAL INFORMATION I have a multi-monitor setup with 2 4k monitors. The main is landscape, and the secondary is in portrait off to the right. I have attached a screenshot to illustrate my exact setup. This worked correctly in the last version of 6.3. This regression happened in the 6.4 update. I suspect it has something to do with my screen offsets. It seems the video ends up centered on the bottom of my primary monitor, despite being on the vertical secondary. I would look into this further, but getting the offset set correctly again is very tedious. Chromium and VLC seem immune to this issue. I am unsure of which component is responsible for this behavior, so I have marked it kwin/generic. -- You are receiving this mail because: You are watching all bug changes.
