Bug 487693

SUMMARY

Short:
When activating the Krita window with `Win` + `<order number of the Krita window in the taskbar>`, all the hotkeys related to Canvas Input Settings don’t work

Full:
When activating the Krita window with the hotkey `Win` + `<order number of the Krita window in the taskbar>` (e.g. `Win` + `2`), activation of Pan Mode and Relative Zoom Mode using the hotkeys is not available. However, if I return to Krita by manually clicking on its icon in the taskbar and not using a hotkey, everything works correctly.

To activate Pan Mode and Relative Zoom Mode become possible again, need to interact with the Krita in some way. For example, open the brush selection palette/docker or the brush settings palette/docker (despite the fact that using Pan Mode / Relative Zoom Mode with hotkeys is not available, opening the mentioned palettes/dockers with hotkeys stay available). Or click on one of the main Krita menus in the upper part of the window (File, Edit, View, …).

The situation in which it becomes necessary to activate the Krita window is when I temporarily switch to another window (e.g. PureRef software window) and need to return to Krita afterwards.

I have now noticed that Line Tool also stops working. I guess the problem is not only with Pan Mode, Relative Zoom Mode and Line Tool, but with some other tools/functions too.
It seems that when activating the Krita window with `Win` + `<order number of the Krita window in the taskbar>`, all the hotkeys related to Canvas Input Settings don’t work, but all the hotkeys related to Keyboard Shortcuts work correctly.

This person seems to have a similar problem: https://www.reddit.com/r/krita/comments/upo0pn/zoom_and_pan_stops_working_sometimes_after/


STEPS TO REPRODUCE

1. Open Krita
2. Create new file
3. Switch to any other window (file explorer / web-browser / ...)
4. Switch to the Krita window using the hotkey `Win` + `<order number of the Krita window in the taskbar>`
5. Try using any Canvas Input Settings hotkey


OBSERVED RESULT

When switching to the Krita window using `Win` + `<order number of the Krita window in the taskbar>`, the hotkeys related to Canvas Input Settings do not work.


EXPECTED RESULT

When switching to the Krita window using `Win` + `<order number of the Krita window in the taskbar>`, the hotkeys related to Canvas Input Settings should work.
