This year, graphics related flags like zero copy rasterizer and out of process rasterization have been recurring problems for me on Win7 using a Nvidia graphics card.
Fact is my experience with Chrome Dev is that it very often has bugs and those bugs can often be attributed to a flag being enabled, but then that same flag in Chrome Stable will be working just fine. Chrome Dev is a different story, the last time it was crashing at startup was just this summer. I’ve never had a problem with Chrome Stable crashing when started.
