AMD PR issue report - blender crash on render

Hello AMD, I am picking blender back up after a few years away from it and am trying to work exclusively with blender 2.80 with eGPU running on Mac with Radeon Pro WX 7100.  Since rendering options are limited, I decided to participate in random bug reporting while the ProRender add-on for Blender 2.80 is in development/testing.  Not sure how often I'll have opportunities to post but hope this is helpful.

I will likely continued testing with the same blend file until a version of PR passes all my render tests and then movie onto a new file for testing.  Note, I will have CPU rendering off and only attempt GPU rendering with all tests.  With this first test, viewport rendering works, image rendering fails.  Details below and attached.  Hope this is helpful!

Regards, Tom

Re: AMD PR issue report - blender crash on render

Interesting.  So viewport rendering works fine but not final image rendering?  This is the opposite of some reports.

Re: AMD PR issue report - blender crash on render

Correct, the viewport renders, rendering image crashes.  I've attached two brief videos to demonstrate.  One note, since testing this morning, I noticed blender had an update this am, so this reply was done using "blender-2.80.0-git20190222.9541ce2c261b-x86_64".

Final render: works (image is bright and clear).

Interactive render: works for 1-2 seconds then crashes but the image is very dark in comparison to the final render.

Re: AMD PR issue report - blender crash on render

The AMD Pro Render for Blender 2.80+ (i'm running 2.82 now) is crashing on my system: AMD Ryzen 7 3700X and AMD Sapphire Pulse RX5700 XT.

It crashes on viewport rendering as well, actually that's where I've been getting all the crashes, since I wanted to preview the materials etc, and on rendering the passes it usually crashes halfway and freezes the whole system, only fixed by restarting the computer. Reports say only AMD cards are affected, and that nvidia users aren't having any problems at all.

I haven't yet tested the full image render, since I haven't reached that step yet. It's proving impossible to work with AMD PR right now with this card due to this huge stability issue, although it's amazing and has a lot of potential. I'd love to see this crash fixed so I could keep using it. Until then I'll have to do with Cycles.
