Symptoms

1. Game starts stuttering/dropping frames after being left open for a period (several minutes up to an hour) of time. Stuttering only noticeable when looking around or moving, seems fine (no noticeable stutter) while watching an animation.
2. Game restored to windowed mode and gets resized when left open, idle, for several minutes. Window can't be resized, preventing certain menu interactions. Can't be resized without setting the resolution through graphics options. Note: using a tiling window manager (dwm) so the window becomes tiled when it is windowed (this is why it is resized).

Reproduction

1. Launch game, click continue, play game for several minutes (may be an hour or a little longer, consistently occurs before 2 hours).
2. Launch game, wait several minutes without interacting.

Additional Notes:

• Other people have reported video playback of cutscenes not working. This has not been an issue for me, but is worth noting due to the format of reports in the issue tracker limiting the title for issues to game title + App ID i.e. we can't have multiple reports for the same game.
