--- Comment #73 from Maarten Baert <misc at maartenbaert.be> ---
I still have the same problem with Wine 5.15, with the NVIDIA proprietary
driver (on a GeForce GTX 660), in SketchUp 2017.

I tried all the workarounds in this thread and some other thinks, these are the
results:

These workarounds all work:
- set environment variable __GL_MaxFramesAllowed=1
- call glFinish() right after glXSwapBuffers()
- call glXSwapBuffers() twice (which suggests that it is indeed a triple
buffering issue)

These do not work:
- set environment variable vblank_mode=0 (does not affect proprietary NVIDIA
driver)
- enable/disable vsync in NVIDIA configuration tool
- enable/disable flipping in NVIDIA configuration tool

IMHO the best solution would be to call glFinish() after glXSwapBuffers() for
all child OpenGL windows. Or perhaps only if glGetString(GL_VENDOR) is "NVIDIA
Corporation" to avoid a performance hit for the other drivers.
