Game Videos show black screen in Full Screen

[Mereinid]

Hello all, when I try to watch a game video, say of a game I am interested in, the video plays fine inside the window of the STEAM GUI. However if I try to maximize it to full screen, the sond keeps playing but the entire screen is black. I have to hit escape to exit it.
I tried to watch full screen on YouTube, Kotako, IGN and FOX News. All of those websites work fine in full screen. It is just STEAM video that will not show video in full screen.
Might anyone know a fix for this.? They have worked up until tonight. Last time I looked at the videos for games, were, I guess, Wednesday or Thrusday of this week. Nothing has changed on the PC's

Thank you in advance,
Mereinid

Messaggio originale di Squall Leonhart:

The linked thread is incorrect, the issue is actually a globally defined MSAA setting, you can rectify yourself by setting Antialiasing - Mode: application - controlled in the Valve Steam profile in NVCP.

I did custom app profile in NVIDIA control panel (this is linux)

I did GLFSAAMode = 0x00
GLAllowFXAAUsage = false

on steamwebhelper not sure if I had to do them all or not.

Didn't even have to restart steam.. Video working again. Nice!
Thanks dude.
