Valve fix the New Big Picture Mode on NVIDIA for Linux gamers

In the latest Steam Client Beta for Desktop released December 13th, Valve has now fixed the New Big Picture Mode not working for those with NVIDIA GPUs along with plenty of other fixes.

Previously, it would try to launch and get stuck and not actually display anything but you would hear the intro video playing. Now it seems to launch just fine, although it feels a little sluggish overall with all the animations and fading effects that it does. Still, nice to have it actually work now though.

They also still haven't yet fixed the issue of it showing what's behind the window when you bring up the Steam menu

Here's all the changes noted by Valve:

General

• Fixed several issues related to popup dialogs being sized incorrectly
• Fixed issue where game hover UI would sometimes get stuck in the upper left corner of the UI
