Hello,
I noticed shortcut keys are dropped / not working when into the LXQT start menu
(or in some contextual menus like PCManFM-Qt menu bar and right click menu).
The problem also appears while the title bar of a window is held with a mouse
press, and moving for example.
This makes impossible to make screen capture of some things, but others
shortcuts like volume keys for example, are also affected in the same
circumstances.
By the way, Print screen key also has to be manually added using "lxqt-config-
globalkeyshortcuts", to link a screenshot program like "screengrab",
"xfce4-screenshooter", "scrot", "gnome-screenshot", "kde-spectacle" or any
other one after having manually installed one of them.
Hoping this may help,
Best regards,
Julien ROBIN
