Can you still reproduce this issue? I haven't seen any other reports.

Can you still reproduce this issue? I haven't seen any other reports.

I can reproduce this as well, although the FPS counter is drawn properly.

Recent Failure Reports:

Edit: Seems to happen randomly. Sometimes when I run the game, the overlay is OK.

@MiroslavR system info?

@NaughtySquid Updated my post.

Thanks for the information about it being random; we'll try again to replicate it here.

These visual glitches only seem to occur when the game is run with FPS counter enabled. I can work around the issue by running the game with FPS counter disabled and enabling it in-game.

Edit: To clarify, I am talking about the FPS counter that is part of the Steam Overlay.

I still have the issues FYI. Ubuntu 16.04, Nvidia 358 driver series.

This is still an issue. I just bought XCOM 2 and facing the same bug. It does not happen every time but is bound to the running Steam session. When I'm lucky I start Steam and the overlay works fine and this for the whole Steam session, no matter how often I restart XCOM2, when I restart Steam it happens again. This happens most of the time but some times it does not.

I looked into the Steam log but couldn't find any errors or warnings which would point to this issue.

Because of the randomness of this issue I restarted Steam several times and run the game also several times each session. Couldn't reproduce that issue on my current system and Steam Beta client.
