This isn't llvmpipe specific right? That call you mention indeed looks a bit odd. The function comment explicitly states Width/Height of the new buffer will be 0 so I don't know why it calls get_drawable_size() there in the first place (probably some leftover from older code). It looks like for pixmaps/windows that information will be filled out later at MakeCurrent time, which will eventually call xmesa_check_buffer_size() which will fill it in. However, for pbuffers this is a noop. My guess is it should be filled out in XMesaCreatePBuffer() instead since pbuffers have fixed size (?). -- You are receiving this mail because: You are the assignee for the bug.
