When in RTX, maps that are placed in item frames can be seen through maps that are held in your hand (applies in offhand too). The outine of the block you face also renders through as well.

Using Geforce RTX 2060 in laptop with Ryzen 9 4000h.

I'm unsure if this has already been put out, as searching for "maps" brings up mention of PBR maps and downloadable maps on the Marketplace. If this is a duplicate report, sorry!
