I have the same issue and I am trying to figure it out.

Steam did download something for tf2 for me earlier, that might have been what caused it. I have yet to verify my game files though. I might also opt-out of the steampipe beta and hope that the official release was launched.

it also screw up the server browser and stuff
im opting out of the beta and reinstalling tf2, see if that fixes it

It may be a problem with HUDs that have custom menus. I'm in the steampipe beta and I run dx8. I use broesel with the default TF2 menu and everything is fine on my end.

I also hear a strange high pitch noise when i move my mouse while my game is open. And I have a bloody nose. Oh dear.

ok, so i was reading the psa about steampipe, just delete/rename sourcescheme.res in your resource folder, it fixes it
props to tophu

which resource folder, the one inside or outside the custom folder?

Whoops nevermind

inside the custom one

fuck foster stop ninjaing me

Huh, removing the sourcescheme fixed it and also seemed to fix my weapons not showing nametag uses in my backpack.

Why did you write all over your stats and can we see your bloody nose?

I use broeselhud with a custom menu and everything works fine for me.

It was the sourcescheme for sure. Although now that it's gone my netgraph text is large and annoying again and I don't know how to make it smaller.

Also no aim.

idk if it's related to this, but i deleted the sourcescheme thing and now water/snow are completely transparent

as in, i can see the entire map beneath both of them

don't think its related
