# LD_PRELOAD does not work well when you want to use Proton (modified version of Wine created by Steam)
# When running the games with Proton, they will fail with:
# "wine: Unhandled page fault on read access to 0x00000000 at address 0xf5c1c2b6 (thread 0009), starting debugger..."
# This is due to a mix of our LD_PRELOAD and Proton's. They add ".local/share/Steam/ubuntu12_{32,64}/gameoverlayrenderer.so".
