That's really weird :). Actually I don't think anything's wrong with your setup, but rather that there's a multithreading bug in dri3 or the app. There's no concurrency protection at all in the dri3 client and I'm not sure that's correct. I think you're the only one seeing this possibly perhaps because you're the first to try it with a heavily multithreaded application. Anyway, I'm OK with commenting out the glFinish() wait for swapbuffers until someone has the possibility to debug this thoroughly. Unfortunately WarThunder doesn't run on vmware's svga driver (yet) due to bugs... It would also be good to try to rule out server side radeon dri3 problems. Perhaps by running it on nouveau or intel...
