An apitrace which can be used to reproduce the freeze would be useful (if possible). In order to get a usable trace you may need to disable GLX_OML_sync_control in winex11.drv because apitrace doesn't support this extension.
Interesting thing, the freeze doesn't happen anymore to me with latest Wine master. I'll try wine-2.14 to trace the freeze, since it can be useful for Mesa developers still.
