Git commit f7ee03d065b4e293746248f749a7965c4321b1cb by Marco Martin. Committed on 05/07/2024 at 12:16. Pushed by mart into branch 'master'. Refactor floating panels * Floating panels are always big enough to fit the floating version * they never move during animations * when they unfloat the masks get updated so that the extra area is completely hidden * the exclusive zone never changes and follows the unfloated geometry * maximize window animations are better, won't resize the window twice anymore * unfloating animation is smoother now depends from https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/2309, https://invent.kde.org/frameworks/ksvg/-/merge_requests/50, https://invent.kde.org/plasma/libplasma/-/merge_requests/1166 and https://invent.kde.org/plasma/libplasma/-/merge_requests/1148 Related: bug 485648, bug 483346 M +1 -0 shell/autotests/CMakeLists.txt M +19 -9 shell/panelshadows.cpp M +2 -1 shell/panelshadows_p.h M +81 -45 shell/panelview.cpp M +0 -1 shell/panelview.h https://invent.kde.org/plasma/plasma-workspace/-/commit/f7ee03d065b4e293746248f749a7965c4321b1cb |
Created attachment 165356 [details] Panel rapid animation behaviour SUMMARY In system settings under window behaviour, in the Movement tab, we can set the size of the snap zone for both the "screen edge snap zone" and the "window snap zone". The panel seems to be considered both a window and a screen edge for the purposes of this setting. Since the floating panel can move, this can cause issues when the window snap zone is larger than the screen edge snap zone. In particular the floating dock goes back and forth between floating and attaching to the screen quickly. I'm not sure if there's any reason why someone would want the window snap zone to be larger than the screen edge snap zone, but it could happen accidentally. For example if you increase the window snap zone while leaving the screen edge snap zone to its default value, which is how I noticed it. Could probably fix this by making the panel only count as only a screen edge, not a window. STEPS TO REPRODUCE 1. Go to System Settings > Window Behaviour > Movement 2. Set screen edge snap zone to some value smaller than the window snap zone (say 15 px and 30 px) 3. Move a window close to the floating panel OBSERVED RESULT The panel attaches and floats from the edge of the screen in quick succession EXPECTED RESULT The panel only attaches once to the screen SOFTWARE/OS VERSIONS Operating System: Fedora Linux 39 KDE Plasma Version: 6.0.80 KDE Frameworks Version: 5.249.0 Qt Version: 6.6.0 Kernel Version: 6.6.13-200.fc39.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 15.5 GiB of RAM Graphics Processor: AMD Radeon RX 6750 XT ADDITIONAL INFORMATION
