So, I am using a blending brush on a project and it works fine for a second and then when I zoom in and hit the space bar to pan, all of a sudden it creates this square shape that resembles a piece of yellow lined paper, which expands as I move my brush, it draws a line within this paper and then when I lift the brush it just disappears.
It continues to do this until I close Krita and then reopen, and then it does the same thing; works at first and then becomes this paper thing.
Can anyone explain to me what is happening here?
Please and thank you!
