Derma elements are not responding to any mouse inputs

Lately, I’ve been having issues regarding derma and mouse inputs. At first I thought it was my Pointshop but Gmod Tower proved me wrong.
I already tried reinstalling Garry’s Mod and that had little to no effect.
Here’s some screenshots of the issue post-install:

PANEL:SetMouseInputEnabled?

Again, this is a reoccurring issue on all servers.

Is a bump needed?
