After making a page, I started to draw, but I could not see the cursor. I could not see the cursor so I could not draw. When drawing, the ink appeared but it appeared randomly. Reproducible: Didn't try
Can you record a video? Your description doesn't sound familiar at all. Also, check your opengl settings and the cursor settings. You selected "other" for platform. Which OS are you using? What graphics card do you have?
Without more information I cannot help you.
Have you been able to reproduce this issue with the newest version of Krita (4.1.1 at the moment)? If yes, we'd need the information requested in comment 1 to be able to triage this further. Thanks!
