Within about 20-30 min of starting illustrator with GPU Performance enabled, everything goes haywire.

It seems to be an issue with UI overlays such as art board bounding boxes and shape paths/points. As you pan about or adjust a shape, it seems that old overlays are not disposed and new overlays are just drawn on top resulting in layers and layers of overlays. The overlays are cleared if you zoom but when you start to pan or manipulate shapes again, the overlays continue to populate on screen.

Images attached should illustrate the issue better then I can describe it. What you are seeing is a single shape selected and the resulting craziness when you pan or manipulate that shape.

The only fix is to disable GPU performance or restart the software.

I'm using a Nvidia RTX 2080 and also have the Intel built in graphics for my 9900k enabled.

I'm at a loss. Illustrator just isn't a professional tool I can rely on anymore. Performance without GPU enabled is unacceptable (1-2 second delays upon zoom or shape manipulation) but the program is just plain broken when I enable GPU performance. Working actively to make Sketch my illustration tool even though I've been PC based for the last 4 years.

I know the devs are working hard but management needs to put more resources behind fixing illustrator.

PS uservoice crazy buggy when using firefox. Couldn't post so had to switch to chromium based Edge.
