Nothing huge here, but it's nice that Valve have finally fixed another issue that plagued Linux users for some time.

For those who don't know, Steam has a built-in screenshot tool (Hit F12 while in-game) and you can then upload them to Steam directly for others to see. The problem is that UE4 games would just give a completely black shot and it's been a bug since as far back as 2014 (possibly even earlier) so it's good to see it squashed.

Here's the full changelog:

Steam Overlay

Fixed screenshots for titles using Unreal Engine 4 in OpenGL mode

Fixed OpenGL API errors for applications using Core contexts

In-Home Streaming

Fixed black/green output for titles using Unreal Engine 4 in OpenGL mode

Fixed upside-down output for some OpenGL titles

That said, Valve still need to solve this bug in relation to their screenshot tool not working a lot of the time for Linux users, but it's likely quite a low priority.
