Hello,
Thank you for your report. This reminds me of a old issue we had some time back and this could be the current problem that you have .
I would recommend that you update your current browser or use a different one like firefox, edge, IE, etc.
Another option is to disable hardware acceleration in the Chrome settings (or for advanced users, just disable the 2D Canvas). It only happens in Chrome in combination with certain graphics cards.
Sorry for any inconvenience caused by this issue.
