Got same behavior, like all textures are converted into solid black color after few seconds or minutes of playing or staying in menu). The game is not frozen, sky is visible, there are colored points of some of light sources (for example two green dots from crosshair at early beginning of the game).
Update: changing quality of RT in menu (even w/o applying them) returns normal picture back for other few minutes or seconds.

Fixed in mesa since commit https://gitlab.freedesktop.org/mesa/mesa/-/commit/d924281c78709f9b930e4392c7971b31ebf5bb79
