I'm having the same problem, and I can't seem to find a solution :c

pawconnoisseur if configured properly it does just fine
Try running r_fullscreen 0;r_noborder 1;vid_ypos 0;vid_xpos 0;vid_restart in the console

If this doesn't work these are instructions for WAW but adapting the paths you should be able to edit the cfg to set these settings

Make sure your game is closed before doing that.
Go to %localappdata%\Plutonium\storage\t4\players
Open the config file with the notepad to edit it.
plutonium.cfg is for singleplayer/zombies and plutonium_mp.cfg is for multiplayer
Change these 4 dvars to be like below (you can use ctrl+f to search for them)

seta r_fullscreen "0" seta r_noborder "1" seta vid_xpos "0" seta vid_ypos "0"

rec fps is 200 max or 60 min, same issue happens in bo2 where you can jump on to the sides of props and float there till you release space bar
