SUMMARY I use mouse buttons on the side of my mouse to go forwards and backwards through webpages etc. pretty regularly, however randomly I will press "mouse back" (whilst the focus of the mouse is still on the specified window, e.g. firefox) but it will bring another window from the background into focus and press "mouse back" on that window instead I am not sure if this is an application issue or kde / wayland in general, but it happens with different applications. I also alt-tab regularly so I am not sure if this is somehow adding to some kind of "active window" confusion STEPS TO REPRODUCE 1. Open a few windows (firefox, discord, dolphin, etc.) 2. Alt-tab a few times. Press "mouse forward" / "mouse back" buttons 3. Occasionally, focus on the current main window will be lost and another window from the background grabs the focus and accepts the mouse input - even if your mouse stays within the main window's area OBSERVED RESULT Focus lost to random background application Mouse event "stolen" by background application EXPECTED RESULT Mouse event should be sent to the current in-focus window Window focus should not change SOFTWARE/OS VERSIONS Operating System: Fedora Linux 42 KDE Plasma Version: 6.5.1 KDE Frameworks Version: 6.19.0 Qt Version: 6.9.3 Kernel Version: 6.17.6-200.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 5800X3D 8-Core Processor Memory: 32 GiB of RAM (31.2 GiB usable) Graphics Processor: AMD Radeon RX 9070 XT ADDITIONAL INFORMATION
Does not occur if Legacy X11 App Support is set to "Prohibited", so this may be related to something like https://bugs.kde.org/show_bug.cgi?id=510404
Thanks for the report. Weird indeed! Bug 510404 has been fixed for Plasma 6.5.5? Can you upgrade to that version (once it's released) and see if the issue has stopped happening?

If I uncheck "Listening for mouse buttons" in the Legacy X11 App Support, then the issue goes away - so for now my workaround has just been to remap my mouse forward button to mouse forward + F24. If Legacy X11 App Support is set to "only the meta keys" (leaving "forwarding mouse buttons" unchecked), then any application that I want to listen for "mouse forward" just listens for F24 instead, and this has been working perfectly for a few weeks now
