As of the new version .337 if you have Dynamic Resolution set in game and use one of the existing presets you get seriously mangled textures when it scales down.
If it scales back up to 1.00x then the image is fine again or if you disable dynamic resolution entirely. I believe you said you implemented new code for this, but wasn't it supposed to ignore it if it wasn't implemented? Here screenshots of what I'm seeing with the Ruby Obsidian Weathers preset as an example:

Also was the FPS display in headset completely removed? I know it wasn't great to look at before, but it was better than nothing. Now it seems it only shows on the desktop window.
