Graphic bug in Linux during explosions and rocket launch

I posted this in steam’s forum but I will repost it here.

The title nearly says it all. all explosions or rocket launch trails appear as a purple blob. I have included a link to a screen shot below.

Yep, same here on fedora 21

Yeah confirmed purple yuckiness on Ubuntu 15.04/nVidia as well

Yeah, this has been around for a while.
While we’re on the subject, the latest hotfix makes the game fail for me after clicking go on the launcher. Player.log says nothing about any errors.

Since i started up steam again since yesterday, there was another update to download. Still fucked for Linux. As said above, nothing in Player.log that looks any different from when it works normally. After hitting OK on the launcher it either goes to fullscreen (or not, tried selecting both) then just closes.
When I run it from the terminal all I get is this.

Guess I’ll check back in a week or two…I’ve noticed lots of fucked shit people are reporting on the windows side and I know Linux gets no love whatsoever when that happens. I WOULD play Legacy to tide me over…but the Linux client was removed for that as well, GG!

Could you guys please get a Linux box to test on? Dual boot is so simple to set up even a Mac user could do it, and the OS doesn’t cost anything. FFS.

3 weeks later…still nothing.
