@Magikarp Check your MatchmakingCategoryMapPanel.res file instead of the clientscheme
Also update your url to this: https://github.com/SteamDatabase/GameTracking-TF2/tree/master/tf/tf2_misc_dir for the current game files
@Koncept I'm 99% sure that is caused by using the high quality item images and resizing them. The skins and festivized weapons don't resize properly automatically anymore since the Smissmas update. The transparency on it is caused by not having "use_item_rendertarget" "0" in the itemmodelpanel section.
Taunt menu is hudlayout.res > HudMenuTauntSelection for positioning and HudMenuTauntSelection.res to customize the look (which would have been easily found by looking for 'taunt' in the default files ;) )
