[BUG] Puzzles are not displayed properly (on some puzzles)

I didn’t try all puzzles but at least for Batman and APU the canvas/WebGL frame is “stuck” or do not show up correctly, with older IDE everything was fine.
Some others like Indiana, Thor works fine.
I checked logs and didn’t see any error:

Firefox 43.0 (almost all addon disable)
I don’t have any flash/silverlight/… installed (<- maybe useless info, but who knows)

Batman (almost stuck):

APU (stuck) :


On qupzilla 1.8.9 APU works but Batman (both) don’t.

Thank you for your report.

We were able to reproduce the bug on Batman and we just fixed it.
However we can’t reproduce what happened to you on APU. Can you refresh your page (CTRL+F5) and try again?

I already did it, but it does not solve the problem.
I will try to see if I can find something on what happens.

I restarted Firefox and all works fine, I guess it was in a buggy state.
Thanks for the quick fix.
