hitting the FULL SCREEN preview on the same 1 monitor seems to turn off ALL the effects. is there a new switch somewhere? is this new? I'll admit, I don't use full screen preview that often, but when I have, never noticed any issue like this.
latest vegas, latest graphics drivers, latest windows, latest windows drivers
HDR10 project, HDR monitor, Windows is in HDR mode, maybe output transform related, but the small preview window looks fine.
