I’ve been experiencing this issue for a long, long time but only now I managed to figure out the steps to reproduce it.
I tend to work very fast. Clicking, dragging, panning and stuff. This leads to me pressing keys in many different ways. For panning, I usually press the spacebar, click and drag it (as you would expect it), but when I’m “in the zone” I invariably end up clicking first and pressing the spacebar a few miliseconds later. When this happens, the whole view shifts to the last mouse position of the last panning action.
These are the steps to reproduce it:
- Pan around a little bit;
- Click and hold anywhere (do NOT drag yet);
- Press and hold spacebar;
- Drag the cursor around.
Here’s a video:
