I can't reproduce it always, i think it's when my memory usage is high (i don't understand much about hardware/gpu) but i have many people saying that it's happening the same when they updated to 58.x and some of then have new PC. For example on this website: https://www.radarbox24.com

I was unable to repro on my workstation and on my laptop. Requesting assistance from test engineer: Please confirm this bug. Most likely you will need a low-spec Win10 machine. Bisect would be helpful. Thanks.
