Description
Pluging a 3rd monitor using a thunderbolt to Dual DisplayPort adapter https://www.amazon.com/gp/product/B01DYFI1OE
It works well on XRender but when I try to enable OpenGL support (either 3.1 or 2.0) it mirrors and corrupts all displays. I'm using manjaro. Here's a quick hardware dump:

This problem is reproducible with KWin and Gnome Shell (this later using X11 and Wayland).
