SUMMARY After upgrading to plasma 5.22.90 on Arch linux, I have noticed that whenever I click on the flameshot icon in the tray, the desktop freezes for 1 second or so before the screenshot tool shows on the desktop. This seems to happen on Wayland - I will check X11 later today and report back. I captured the below log: 9/16/21 2:45 PM plasmashell Got invalid activation app_id: "" 9/16/21 2:45 PM flameshot qt.qpa.wayland: Wayland does not support QWindow::requestActivate() 9/16/21 2:45 PM flameshot QPainter::begin: Paint device returned engine == 0, type: 2 9/16/21 2:45 PM flameshot QPainter::setRenderHint: Painter must be active to set rendering hints 9/16/21 2:45 PM flameshot QPainter::setCompositionMode: Painter not active 9/16/21 2:45 PM flameshot QPainter::translate: Painter not active 9/16/21 2:45 PM flameshot QPainter::setPen: Painter not active 9/16/21 2:45 PM flameshot QPainter::setBrush: Painter not active 9/16/21 2:45 PM flameshot QPainter::setBrush: Painter not active Operating System: Arch Linux KDE Plasma Version: 5.22.90 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2 Kernel Version: 5.13.0-1-amd-staging-drm-next-git-00935-gb44d240c34d2 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 3700X 8-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: AMD Radeon RX 5700 XT
Note: this only happens when the flameshot window is to be displayed on the desktop; if I cover the desktop with a full screen application such us thunderbird, there is no freeze. I also tried with the Info Center application and again, no freeze.
I cannot reproduce on X11. Seems to be fine there.
I could not immediately reproduce this. Can you run "Q_DBUS_BLOCKING_CALL_MAIN_THREAD_WARNING_MS=1 plasmashell --replace" and try to reproduce.
I did as you asked but there is literally 0 output during and after the hang when I run plasma with this var. I also just updated to 5.23.90 and the issue persists. Anything else I ca do?
Created attachment 145433 [details] plasma workspace I spent some more time on this and the freeze might be related to plasma workspace saving a screenshot to /tmp/ everytime I click on the flameshot icon. see attached
ok, found this: https://github.com/flameshot-org/flameshot/issues/2032 specifically, this response: https://github.com/flameshot-org/flameshot/issues/2032#issuecomment-961340796 I guess it's a bug in flameshot, not KDE.
