libGL error when running openroad -gui from within docker

[oharboe]

I'm running openroad -gui from within Docker and I get these errors. I think they are harmless, but the OpenROAD GUI sometimes locks up if I resize.

$ openroad -gui
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

This is the error from OpenROAD GUI just as it locks up:

[WARNING GUI-0076] QXcbConnection: XCB error: 2 (BadValue), sequence: 1235, resource id: 1064, major code: 130 (Unknown), minor code: 3

Reproducing the lockup on the developer end has proven impossible so far, so this question is specifically about the error above.

I've seen that warning before but it seems benign and has never cause any trouble. I have no idea what it means but I doubt it relates to your missing libraries.
