While working on a picture, doesn't matter much which picture it is, I notice after I finish a stroke or two with the pen the circle around the cursor tends to just freeze in place even if the cursor itself has been moved away, and I end up having to 'click' to get it working again. That's a problem I only just today started running into, this is while using Windows 7 with a Wacom Bamboo tablet. Hope I explained well enough.
Edit: I just realized it's probably wise to say which version of Krita I am using. It's 3.3.1, and this issue goes even when I remove the preview circle or change it around. It's kinda like it's lagging, but not at the same time.

Edit: Alright, I tested on another computer. Same version of windows, Krita 3.3.2, no problems. Once I returned to the main pc, re-installed Krita and made sure it was up to date, I still had the weird issue. Seems like it might be a form of glitch but I'm not sure, the cursor will stick sometimes, when I go to draw or color something it seems like it doesn't want to register the pressure correctly, if at all. If I need to move this to the Glitch forum thing, I will, but for now I'm not sure what it is, I just know now it isn't my tablet or pen. Also, I have the same Krita settings for both computers, both being Windows 7 and updated.
