Re: Very low framerate when recording desktop content in Weston using mesa git on Radeon 5770 (glReadPixels slow path?)

Doing some debugging, it seems the call to ctx->Driver.ReadPixels()
in _mesa_ReadnPixelsARB leads to _mesa_readpixels() being called in
readpix.c.

I'm attaching some output of gdb that will hopefully be useful.

I'm also attaching the debug terminal output of running Weston with the DRM
backend.

Let me know if I can provide other useful information.
