Please describe your issue in as much detail as possible:

After the latest update a few weeks ago my UI became transparent, making the client very hard to navigate and use overall.

After some asking around on Reddit i found a possible fix, not sure if it will last. But in the nvidia x-server settings, i turned off FXAA and then i rebooted steam, now the UI looks like normal again.. and I could see that the client had a brand new UI.

Steps for reproducing this issue:

1. Turn on FXAA (if not already turned on) in the nvidia x-server settings.
2. Reboot steam.
3. That should be it.
