there's no display glitch or anomalies ever if 3D graphics aren't involved (at least that's my conclusion).Please help me think this through and know for sure! I'm 85% sure that it's a hardware failure, the following gives me some doubts: Opened Chrome and went to Google Maps and.

So I popped out an old backup drive from last year (way before any issue began) with High Sierra on it, and booted from that. Since the problem seems, for now at least, contained, I thought it might be a software issue.

Geekbench 4's GPU benchmark runs fine too, but it doesn't actually draw anything on the screen. But the instant I try to run 3d graphics by launching a game, or enabling acceleration in Chrome, the problem comes back. Mac OS boots fine and runs fine, my music software runs fine, and with Chrome in which I deactivated hardware acceleration, all web pages run fine, including 3d pages like Google Maps. Check the crash logs every time: Graphics hardware encountered an error and was reset: 0x0000002bīut the thing is, other than that there no display glitch whatsoever on any application.

Looks like anytime 3D graphics are intended and the discrete GPU is used, it crashes. I then got the idea of trying to put any 3D graphics on (Steam games, Google Earth etc.), and yep, all that crashes too. MacBookPro9,1 running Mojave, connected to a external display most of the time.Ī few weeks ago I noticed that anytime I would open Google Maps, the page would freeze and crash, while displaying small untextured triangles.
