SUMMARY Ever since upgrading to plasma and KWin 6, there is a weird behavior with clicks "falling through" windows. I have noticed it in Firefox, not sure if other programs are affected. STEPS TO REPRODUCE 0. Have KWin's "Quick Tile Window to the Left" bound to `Meta+Left` 1. Have Firefox open 2. In quick succession hit Ctrl+N and then Meta+Left 3. Click on the tab/title bar OBSERVED RESULT The click is registered by whatever was behind the Firefox window (in my case, a different Firefox window) EXPECTED RESULT Click registers in the new window SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.0.1 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.7.9-arch1-1 (64-bit) Graphics Platform: X11 Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 62.7 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 3070/PCIe/SSE2 ADDITIONAL INFORMATION When moving the window, there seems to be an animation which is aborted halfway through. I don't know what animation it is, but it seems related. If someone could tell me how to disable it, I'd happily test without.
I can't reproduce with the provided steps on 6.0.1, X11, arch linux. This might be a duplicate of BUG 482687, which will be fixed for 6.0.2.
I'm not entirely sure if this is related to 482687, as I have a panel on the left edge of the screen. Which, now that I check, left side is the *only* side I have a panel on, and this does not happen if I test with quick tiling to other screen edges. Nor does it happen when I maximize a window.
Tested in 6.0.2, and indeed it's fixed now.
