What games do you have mounted? Also, does this happen on all maps with lighting?

The usual like tf2, hl2, ep1, ep2, Lost coast, l4d2, portal, cs:s, portal 2, CS:GO. I've home to speculate that it's only lighting used in hl2. It doesnt affect all maps and not all lights, some lights are fine.

Can you try it with only CS:S and HL2 mounted?

Nah no fix

You restarted your game after unmounting them, right? If so, disable your workshop addons and remove legacy addons in garrysmod/addons. If that doesn't work, delete your garrysmod/download/materials and garrysmod/materials folder; backup anything you'll want to keep.

Looks like missing sprites. What a weird problem.

Check if you have cinematic mod. Because if you have that, the lens flares on lamps look different. You maybe winded up deleting that. I would suggest reinstalling gmod though.
