The game Firewatch is missing some elements from the menu with git. On older releases (11.x) the elements are there, but with issues.

Bisecting for when the elements went missing leads to

I made an apitrace of the problem, but replaying it doesn't show the bug. (Probably because the game uses glXxxpointer)

Something about the bug seems to connected to fullscreen, sometimes the elements that are present in 11.x goes missing when not running in fullscreen. Othertimes the game or gnome-shell crashes when switching between window/fullscreen.

This also happens on Evergreen.

All scrolling UI elements (the slots in the load/save/new game menus, display resolution list in the settings, text in the in-game object viewer) aren't displayed when the game is running at native resolution. If you switch to a resolution lower than native, then the text is rendered correctly but isn't properly clipped to the containing UI element. I've never seen any kind of glitchy rendering as demonstrated in the attached screenshots.

Good catch, I have the same behavior on i965. 

So possibly a game bug or something general to Mesa?

Comment 4 Marek Olšák 2016-10-17 21:13:31 UTC

Does it still occur with current Mesa git?

In native resolution it actually seems fine on both 12.0.3 and current git (also fine on i965 with 12.0.3). 

The problem with clipping in non native resolution persists, but it seems to be either a game bug or something more general to Mesa.

I'm fine with calling this FIXED.
