I had tried to force an Xorg+Mesa stack without my userspace patches to hit this error when testing, but must have missed some permutation. If the stalled Mesa patches go in, this would stop happening of course, but those were held up for a long time in review, and are now waiting on me to make some modifications. Are you using the modesetting driver in X? If so, with glamor I presume? What version of Mesa? Any distro patches? Any non-default xorg.conf options that would affect modesetting, your X driver if it isn't modesetting, or glamour? Thanks, -James On 6/30/20 4:08 PM, Kirill A.
