The fullscreen HUD (normal status bar is fine) disappears if a cameratexture is in the field of view of the player.

Affects all renderer modes except OpenGL.

Edited the topic title for clarity. I was confused, at first.

I can't say I'm seeing this with 3.5.1 (and a git build from yesterday). I've tried a few different HUD and scaling options. The HUD remained visible at all times.

You have to have screenblocks==11 && ( 0 <= vid_rendermode <=3 ), it will render just fine if you use the status bar or OpenGL mode.

Ah, that was it. My vid_rendermode was not in that range. I can see it now (or, rather, I can't see the HUD now as long as any part of the camera texture is in my FOV).

Fixed. Another instance where global state was set in a wrong place - par for course for nearly all code originating from the software renderer.
