Win10, Crimson 17.2.1, AMD 7870 2GB, blender-2.78-f49e28b-win64

Steps taken:

Render scene

open Vieport shading Rendered
Render scene again

s.blend

I have tested with previous drivers. I haven't test split kernel branch.

OpenCL error occurs after I open Vieport shading Rendered. Also, I don't understand why 2GB GPU memory is not enough on second time to render a cube on 512*512 tile size. Before in 2.76 I didn't have similar issues. Why is 2GB memory insufficient ?

Also, I have noticed that Blender is waiting render kernels to load twice: first when rendering the scene, second when opening Vieport shading Rendered.

I don't know if I should open new report for this but I can't render anything with GPU.

Instant crash whatever I render. Even default scene.

Loading kernels takes long. Sun lamp with white color and strenght set to 2 is yellow. How can this be?

Latest Blender version and latest AMD drivers on Win10.

@TomG Please open new reports for new issues, putting different issues into the same report is quite confusing.

Is the original issue fixed in latest master?

How was this issue fixed? I'm still getting the same issue with the RC1.

It wasn't. Blender no longer supports AMD 7870 because of the driver incompatibilities.
