Maximize safari (this is on a retina macbook, which might be relevant). Load up the link, maximize the window, press x to start a new game.
You're in control of the little white dot moving on a blue background. If you move around the arrow keys, after 10 or so moves the whole screen suddenly becomes white. I don't know what's causing this - somehow the canvasses for the tiles are getting messed up. I can't tell 100% that this isn't a bug in my engine, however
1 - It doesn't happen in safari 7.0.3
2 - It doesn't happen on chrome or firefox
3 - It doesn't happen if you have the debug window opened (either on the panel below, or in a separate window).
4 - no error messages are generated by safari that I can see
The engine's quite complicated - it would take a lot of work to put together a test case, but I hope mentioning this is still of some use - let me know if I can be of any help.

I am unable to reproduce the issue of "whole screen becoming white" using attached URL game and I even tried moving dot rapidly using "Z" key to redo as well in succession with arrow keys. I am using Safari 15.5 on macOS 12.4 to test this issue.
I think something along the line might have fixed this issue. Appreciate if this can be closed with "RESOLVED CONFIGURATION CHANGED" tag? In case, if my testing is flawed, please retest accordingly. Thanks!
