For some reason I'm getting horrible crashes on my app (has worked great for months. Still works great on Linux and Windows) since chrome switched to gpu rendering for everything. I haven't found the issue yet but it's really odd.
I had really bad crashes (high pitch noise, bright white flash, driver killed) on Firefox 4 and Chrome 7 when they started to use HW acceleration and problems went away after the update.
No luck on that, I checked and there was in fact a graphics update but that didn't affect the behavior. My next step is to try to figure out what is causing it to make a bug report.
