RPR 3.1.0 blender crash on Viewport Shading mode

Hi
I had a problem with Viewport Shading materials and rendered mode, they crashed my blender. I decide to upgrade all versions of my configuration now I use Blender 2.92 and RPR 3.0.1 But I have the same problem with last versions.

My setup Macbook Pro 2,6 GHz Intel Core i7 16 Go DDR4 with a AMD Radeon Pro 5300M 4 Go.

On render properties :

• RPR : activate
• CPU : disable
• AMD Radeon Pro 5300M : activate
• Separate viewport and preview… : disable

On View layers properties

• RPR Denoiser : disable

Tested with render engine Cycles and I have no problem but my CPU don’t like it !

I wonder if this is not a problem in my RPR configuration.

Hey @rmybld, just to let you know I did not find any solution. I just bought mac mini with M1 silicon chip. Works great with both CPU or GPU cycles rendering. Did not test which is faster tho. Hope you will find solution for this issue. Heads up 😉
