Game launched but invisible

When I launch the game, I have an empty window. Everything "work" (I can click on buttons even if I can't see them, I hear the click and if I load a world, everything shows in the log). Also tried to delete option.txt.

Drivers up to date, no issue with the previous snapshot.

I forced a crash to generate a log with F3+C

EDIT: A reboot of my computer fixed the problem. No idea why though.
