Krita input progressively breaks over time (all versions, no consistent trigger)
I’ve been experiencing a bug for several months now where Krita’s inputs progressively stop working over time. Specifically all shortcuts for zooming in and out except ctrl + = and ctrl + -. This includes keyboard shortcuts and tablet shortcuts like pan/scroll. It also includes rotating the canvas with the mouse but not rotating the canvas through ctrl + [ and ctrl + ]. It happens across every version I’ve tried including 5.x, 5.4.0-prealpha, and Krita 6, and persists through reinstalls, so it doesn’t seem to be version or installation specific.
What happens:
Inputs don’t all break at once. It starts small for example zoom stops working, or panning stops working. Then if I try to use something that’s already broken, it seems to cause more things to break, until almost nothing is working. It always happens between actions rather than mid-action, so an action that has already started will complete, but starting a new one fails.
After a while it will just… resolve on its own. Sometimes it’s gone for a month, then it comes back. There’s no consistent trigger for it starting or stopping.
The things that sometimes trigger it:
• Randomly mashing buttons on the keyboard
• Being afk
• Tabbing to other programs
• playing games with krita opened in the background
• Opening programs like task manager and settings
What I’ve ruled out:
- Tablet drivers / tablet hardware: happens with tablet fully unplugged, drivers manually closed, no tablet service running, just mouse and keyboard
- Always-on-top applications: happens without them too
- Windows Update activity: updates are essentially manual, no background update activity
- Screensaver / power management: neither are in use
- Modifier key phantom holds: pressing all modifier keys during the issue does nothing
- Clicking the canvas to restore focus: does not help
- Switching windows and back: does not trigger or fix it
- GPU/tablet driver updates: same drivers throughout, no changes between when it starts and stops
- Windows Ink interference: happens regardless
