--- Comment #10 from Sergey Isakov isakov-sl@bk.ru --- May be you are right and this patch influenced on me indirect way. Anyway my setup. This is not linux, there is no bumlbee and glxinfo. I am using iMac12,2 with AMD Radeon 6000. OSX 10.9.5 with stock drivers. Wineprefix is hidden from me. I installed Wine into Wineskin and sure it changed every time when I ask to do this.
The bug was reported with wine-1.7.39 and remains here up to 1.7.54. Yes, I can compile unmodified WineHQ from latest git. As well, I can compile unmodified WineStaging from git sources from https://github.com/wine-compholio/wine-patched I also has my local sources with unapproved hacks and patches. For example your patch 39057. Doing this I found the log is clean from the messages of this bug. Checking latest changes I found this patch. Now test: took WineHQ-1.7.54. The bug presents. Apply patch-39057. The bug dissappears.
If you proposed I made a mistake then I will repeat this process again using latest git version.
