--- Comment #1 from Samuel Pitoiset samuel.pitoiset@gmail.com --- Very interesting stuff! It's similar to the TW3 issue (https://bugs.freedesktop.org/show_bug.cgi?id=101731).
Basically, Wine doesn't correctly set the transform feedback varyings (ie. count is 0 in glTransformFeedbackVaryings), then MEsa

--- Comment #2 from Samuel Pitoiset samuel.pitoiset@gmail.com --- [..] then Mesa reports the following errors:
Mesa: User error: GL_INVALID_OPERATION in glBeginTransformFeedback(no varyings to record) 358502: message: major api error 4: GL_INVALID_OPERATION in glBeginTransformFeedback(no varyings to record)
and the GPU hangs.
If you try the "special varying hack" patch from #101731 it fixes the issue.
