UPDATE: I completely forgot to come here and report that the issue is now mostly fixed since the update. Only default values seem to be busted, but that could just be an issue I caused by my tinkering. Editing only the OP rather than making a new post because I don't want to bump this topic.
Old post:
Is it just me, or do the brightness, contrast, and gamma sliders not work in BGFX anymore. I didn't do a clean update, just a drag and drop, if that might be the issue.
