not during this jam, though I had other types of rendering glitches on this laptop during previous jams,
but typically in 3D games in the web format. In these cases I played the downloadable version if available, which didn't have these issues at all.
I am pretty sure it is related the the age of the computer, it doesn't support the newest technology anymore. This is something I also get to feel, when I want to do something graphics heavy like rendering, it is barely possible on the laptop, so such work I do on my stronger desktop pc if available.
Otherwise I had one more minor issue on all (or most ?) games, and that is that the full screen button didn't work as well.
