I don't know about everybody else here but speaking for my self I can honestly say that I'm not knowledgeable enough to file an issue about these sorts of things to google.
They have smart engineers who regularly deal with "my website doesn't work" type bug reports. If you point them in the right direction and clearly explain what the issue is, they can probably figure it out.
Is it not also in Scirra's interest to help their customers in situations like this even if the fault isn't with Construct?
We regularly do - I've filed many issues with every major browser vendor - but we have not observed this issue ourselves yet, which means it's best for the affected users to report it. Dealing with a bug often involves a few rounds of back-and-forth "try this... how about this..." If we can't observe it then we're not much use in answering that.
Besides, it's a useful thing to get familiar with doing. If you have browser-specific issues or you feel that for some reason we're not doing enough about something, you can bypass us and go direct to browser vendors.
I'd also add graphics driver bugs are absolutely nothing new; they've been regularly cropping up on all platforms for years. We've never added any settings in response. The browser GPU blacklist is the way this has always been dealt with, and this case is nothing new. It's been 28 days, someone should at least try filing an issue.
