GTX680 MacOS 10.14.2 Mojave — video glitches & artifacts

[jsts]

Just installed a clean Mojave on an external SSD. I decided to share with you how its GUI works.

My specs: Mac Pro 4,1-5,1 (2009) 2x Xeon X5690 96GB RAM 1333Mhz 1x Flashed EVGA SC GTX680 2GB (Slot1) 1x Apple LED Cinema Display 1920х1200

Try another card, I'm using 670 without any issues via 2x Dual-link DVI's.

I have two MP5,1 with GTX 680s, never got this artefacts, just the ocasional black block in Finder file lists and rarely near the menu clock.

@jsts I think your card is failing.

But in previous versions (Lion to High Sierra) no GUI issues present... :-/

Mojave now uses METAL to interface with the GPU, your GPU could have a problem with METAL unit and not with the OpenGL one.

It’s a more taxing OS on the GPU.

Zotac 680 4Gb flashed and now problems in 10.4.2 or 10.4.3.

Also hooked upto a 24” LED Cinema Display via DisplayPort.

Would suspect that more likely your card rather then a generic thing with 680 cards.

I see... Thanks, guys.

Hmm. If it worked before but not now seems odd. Maybe do a vanilla install with the drive mounted internally just to check?
