Black rectangles

[antonkudin]

When working sometimes black rectangles appear on canvas in random places, as a rendering glitch. They go away only if I zoom the canvas.

Ive seen these in a lot of versions, not just latest one.

My iMac isn't metal-enabled and I have "Display" set to "OpenGL".

Managed to catch them, so here's couple gifs:

Hi @antonkudin,

Sorry for the delayed reply. 

Have you got a recipe to replicate this by any chance? 

Thanks,

Gabe.
