--- Comment #1 from Olivier F. R. Dierick <o.dierick at piezo-forte.be> ---
Hello,

--- snippet from attachment 72711 ---
0138:err:d3d:wined3d_debug_callback 014848B8: "GL_INVALID_OPERATION in
glFlushMappedBufferRange(buffer is not mapped)".
--- end snippet ---

Performance issue with GL buffer mapping reminds me of bug 50235 and bug 52334
(more likely the later).

Can you try reverting the regression commit from bug 52334 and report whether
it makes any difference or not?

Regards.
