My significant other uses Windows 10 64bit, Krita 3.0 (Korean ver.) and Wacom (doesn't know the model name).

Until couple weeks ago she had no problem using Krita and her tablet. However, starting yesterday when she opens Krita, the circle at the edge of painting area doesn't move neither by her tablet nor her laptop mousepad. The program still recognizes both when the cursor is out of the painting area but it doesn't all of the sudden when it is on the painting area.

She tried to remove and re-install the program few times already but the malfunctioning is still problematic. Is there any solution for this?

Thanks in advanced.
