Description tomtomtomreportingin 2022-05-01 19:25:01 UTC

SUMMARY
In Krita 5.0.5 and 5.0.6, using xdotool (https://manpages.ubuntu.com/manpages/trusty/man1/xdotool.1.html) to move the mouse will break canvas input usage, until the dockers/menus are interacted with or alt-tab is used. It's possible this is related to other cases of canvas input breakage, for example as described in  https://old.reddit.com/r/krita/comments/ufw4x3/krita_506_shift_space_and_mouse_right_click/ , especially as this breakage does NOT occur in Krita 5.0.2.

STEPS TO REPRODUCE
0. Install xdotool
1. Create an executable bash script with the following code:

#!/bin/bash
# requires xdotool package
xdotool mousemove 1080 700

2. Bind the executable script to a DE shortcut.
3. Move Krita to the right half of your screen.
4. While cursor is over Krita, execute the script using the DE shortcut.
5. Attempt to use any canvas input shortcut.

OBSERVED RESULT
Nothing happens.

EXPECTED RESULT
Canvas input shortcuts should still be usable.

I can't reproduce this :(. The keys I bound this to were: Ctrl+d and Super+b, non of them broke canvas input shortcuts. Maybe I can try this on KDE plasma, what is the shortcut key you mapped your script to?

I initially encountered this using Alt + Space for my mouse movement script, but whatever keys I decide to change them to seemed to cause breakage from the script regardless.

Oh, it seems I CAN'T reproduce the issue when binding it to Ctrl + D, but I CAN reproduce the issue when binding it to Meta + B, so it might be key-specific in some weird way.
