Team Fortress 2

Hey, has anyone heard of a problem with some source engine games that you have to manually preload 32bit libtcmalloc in order for the games to function? It happens at least on arch and fedora according to my system and everyone on protondb... The issue started back in summer and never got resolved. I used to use it but I read on the initial github issue that there is a chance you get vac banned. I am now scared and hope all my hours don't go to waste on tf2. Sorry for that. I now have been dual booting linux for gaming on windows because of issues like these. Maybe I'll try debian or kde neon...

This isn't some sort of asking for help, just a weird thing that I am worried about and want an oppinion somewhere I think people will say something...
