When opening a weapon screen directly from the vault and switching to the weapon's shader screen, all but the first screen of shaders are empty, and in the first screen there are gaps (i.e. not all shaders are being shown). Other gun properties (e.g. weapon perks) may also not be shown.
PC, Steam version.

Having the same issue, also with Steam on PC. Noticed the frame rate also tanks when viewing weapons in the vault. If you go to the third page of shaders, the picker UI then locks up.
