SUMMARY
When saving or opening files on a canvas the space key stops working, a key that works to move the canvas as well as the "ctrl" key, which combined serve to zoom in or out of the canvas

STEPS TO REPRODUCE

1. Open Krita.

2. Create a new file or open an existing one.

3. Use the space key or Ctrl + space to pan or zoom — it works as expected.

4. Save the file or open another file (while a canvas is already open).

5. Try to pan or zoom again using the same shortcuts.


OBSERVED RESULT
The space key and Ctrl + space stop working entirely. Panning and zoom shortcuts do nothing. Only restarting Krita restores functionality.

EXPECTED RESULT
The spacebar and Ctrl+space shortcuts should continue working after saving or opening files.

ADDITIONAL INFORMATION

I initially thought it was a hardware issue, but it only happens in Krita.

No custom shortcut remapping involved.

Restarting Krita is the only way to fix it.

Happens consistently.
