UI Text messed up on 2nd display/video card Mac
Closed, ArchivedPublic

Description

System Information
OS X 10.11.6 Titan X 12GB + Radeon XT 2600

Blender Version
Broken: 2.79
Worked: Always had this problem (years), sorry for not reporting before...

Typically I run my mac (classic mac pro) with 2 video cards and run my secondary monitor off the basic Radeon card, for boot menus etc.

If I drag or duplicate the Blender window across to 2nd display I get garbled UI text. Bring it back to primary display, I can read it again. Works normally if both monitors connected to primary card.

I had similar problem with my MacPro, GT120 that was the original with MacPro, and then GTX760 series card. It seemed to be driver issue.
Are both cards so called "mac versions" (firware is for mac)?

In the past I had a GTX660 pc card (unflashed) alongside the Radeon original mac card. Now running a (non official) mac flashed Titan with Radeon card.

Strangely it's the 'original' mac cards that seem to show the issue, when set up with secondary monitor.

@Arto Kitula (akitula) will let you handle this one then.

@Dalai Felinto (dfelinto) would want to try out, but I gave my GTX to my son for gaming purposes and don't have the setup anymore.
@Stephen Hamacek (hammers) Could you try this? If you need build, just ping me and I'll do build to try out (if buildbots aren't working)

I just tried this build from builder.blender.org. Not sure if this is the one I need to try: blender-2.79.0-git20171022.57a0cb797d6-x86_64

Unfortunately the garbled text remains. Let me know if there's a different build I should try.

I'll do a build for you.

Thanks @Arto Kitula (akitula). Just tried your build and sadly the glitch remains.

I thought I'd do a screen capture from my main monitor, in case that sheds any light on things somehow:

Archiving since this is different code in 2.8, and we no longer officially support this macOS version and GPU.
