Re: 173.14.30 Fix needed pronto
Sorry, I haven't the faintest idea what a GLSL rendering pathway even is. I imagine the developers posting in the bug report I linked to above could give you a clearer idea of what the driver is doing different now than it did before.
Unfortunately what they consider a 'fix' is to simply disable all hardware acceleration of the desktop. From what I can tell they've closed that bug and moved on and there won't be any actual fix until the driver changes.
I've got some logs but they don't seem to contain anything revealing other than leading one to that and a couple of other similar bug reports.
