Summary: canvas drawing problems
Product: WebKit
Version: 528+ (Nightly build)
Platform: Macintosh Intel

OS/Version: Mac OS X 10.9
Status: NEW

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.
