The 2nd bug report includes an xfwm4 patch, even. The first one also contains a patch, but it has been integrated into later mesa releases, in particular the one we are using. > I wonder if Xfce before the recent updates (so before > 8549e0ca6fd68a57253471436de49b88b2d47e64) works better. > Andreas, if you feel like it, could you try: > guix pull --commit=97ce5964fb5d52cf2151fea685e28fa23a98b264 > sudo guix system reconfigure … Indeed, the problem disappears with this commit; I can log in and out and in again with xfce working.
