I'm a little confused now - these 3D previews come from the different blender versions (yours and official 2.78)
but obviously the bottom one, which is the experimental one, is different.
This has absolutely nothing to do with this bug, but I'd just like to know why that is

I doesn't contain any other stuff so it should be safe. Now that the fix is committed, tomorrow's build from builder.blender.org and 2.79 will have the fix as well.

I don't have a Windows machine to test, but perhaps P506 can solve it. Here's a build with that patch for testing:

Marin Myftiu (mm25) added a comment to T50856: Blender is not responding after minimizing [AMD].

I think I got this...had this hapening each time I turned off the discrete (AMD) GPU of a laptop to use only the apu: switch back to dual graphics and no problems.
Looks like triple buffering in User Preferencs > System > Window Draw Method is to blame and it should also be the one selected in ' Automatic'. All other options do not cause the freezing. Another thing I noticed is that it makes no difference if you enable triple buffering in your gpu driver options, it just doesnt like it on some models :P
Hope that helps...

Shujaat (Shujaat) added a comment to T51576: Blender crash when change to edit mode with Intel GPU.

Just to add a bit of extra info in case it is useful, blender 2.8 crashes for every engine on my machine, not just Eevee. I have tried BI, Clay and Cycles. Pressing TAB on the default scene using any of these engines crashes Blender immediately.

I don't know why this is not getting enough attention. We should manually make Blender use Overlap as 'Automatic' when it detects an affected card.

That said, I can't get a working matcap even with 2.77a. Can someone that has matcap working in 2.77a let me know the exact driver version you are using?

Mai Lavelle (maiself) added a comment to T51659: OpenCL issue with AMD 7870 and B3D 2.78.5 build.

We will be dropping support for GCN1 because we cant fix these issues for a variety of reasons:

  • I don't have a GCN1 card to test on or try to find a workaround.
  • Everything seems to be fine on GCN2 and 3 as well as Nvidia OpenCL, so we know the kernels work.
  • That means this is most likely a driver bug, which is something we cant fix anyways.
  • It seems that AMD hasn't provided updates for these cards in a while now.

No this is on the hardware level and not software so the GCN (Graphics Core Next) version will not change.

Coukd you leave the compatibility requirement for 7870?
Maybe someday AMD will change the drivers so that issue will be fixed. I have been writing the feedback to them often.
