I'm afraid we are out of time to fix bugs that introduces major d3d regressions. I've yet to see a single patch that addressed those issues.
It's time to start reverting bad commits and testing the results.
The bugs I'm talking about: Bug 10580 Bug 11584 Bug 12794 Bug 13101
Vitaliy.
Regarding 13101 that bug is an Nvidia driver bug. The code itself is really correct and there are more cases in which the issue gets triggered (not just multisampling). I need more testers (I added comments to the bug) to reproduce it on different systems, games and driver versions so that I can create a good bug report to submit to Nvidia.
