deleting the shader cache helps, sometimes it doesn't. I think
MESA_EXTENSION_OVERRIDE=3D-GL_ARB_get_program_binary helps.

Usually export LD_LIBRARY_PATH=3D... LIBGL_DRIVERS_PATH=3D... to another me=

build, starting the application once and then starting it with the system m=
esa
again helps. It could be related to mesa first deleting the other shader ca=
che
before making a new one. Some weird race condition?

Applications I've seen affected:
sddm-greeter (segfaulting)
plasmashell (segfaulting
systemsettings (rendering black window content, segfaulting)
krunner (rendering breaking, segfaulting)

As far as I can tell it doesn't happen with mesa debug builds...

More investigation is needed.
