For what it’s worth, I have this same problem! I posted back in January (complete with a video demo!) but my post didn’t get much traction. ![]()
It’s not just sometimes either. I can reliably reproduce it every single time. I’ve tried it on multiple Mac machines too: one 2018 MacBook Air, a 2017 MacBook Pro, a 2020 MacBook Pro. etc. Oddly enough, if I trigger this bug and then open the tablet tester, my pen strokes register there just fine. I can even click around the UI and it’s nice and snappy. But the canvas itself becomes completely unusable.
Also none of the previously mentioned suggestions work:
- Hitting the escape key
- Using CMD+plus and CMD+minus
- Using the normal trackpad to “unstick” the zoom
- Clicking outside of the canvas/application
- Turning off the “touch” features of the tablet so that only my pen will register input
I even ended up contacting Wacom and they had a technical support person walk me through tons of debugging steps, none of which worked. ![]()
Even the logs show nothing of note:

The Log Viewer docker tool shows even less (with all log categories enabled). ![]()
EDIT: I filed a bug on the KDE forum.
