Apps that worked perfectly last week no longer work at all: Flightgear and Ysflight. Flightgear complains about not be able to produce image and segfaults out. Ysflight complains about double buffering.
I am using Debian's NVidia driver (270) from Sid so the "native" glx's are diverted and nvidia-glx is used. This has not been upgraded recently. So where to file bug? Libgcc?
