Describe the bug

When I start helm (the synthesizer), I get MESA errors:

libGL error: MESA-LOADER: failed to open iris (search paths /run/opengl-driver/lib/dri)
libGL error: failed to load driver: iris
libGL error: MESA-LOADER: failed to open iris (search paths /run/opengl-driver/lib/dri)
libGL error: failed to load driver: iris
libGL error: MESA-LOADER: failed to open swrast (search paths /run/opengl-driver/lib/dri)
libGL error: failed to load driver: swrast

and the window opens, but the GUI doesn't show.

Additional context

Similar to #87967, when I use LD_PRELOAD to load libstdc++ from gcc-9 instead of gcc-8 it works!
