[MSEide-MSEgui-talk] KDE Neon, TrayWidget and "not decorated" error instead of popup
I have problem with popup in traywidget which worked fine so far. Don't know what broke it because I didn't execute this popup for a long time, very probably my KDE Neon upgrade from 16.04 to 18.04 few weeks ago. KDE Neon is ubuntu based on fresh KDE Plasma releases (but in stable branch) and newests Qt libs so maybe there is some regression.
Attached demo and screenshot. When click on traywidget (using left or right mouse button) my whole plasma desktop freezes for a ~5 seconds and then I get this "not decorated" error. GDB break in:
