Understanding Viewport Renderers and Troubleshoots

Hi Society!!

I have been having issues with the viewport renderers in Maya for some time but I now find myself in need of help and hopefully solutions as I reached my threshold of patience . I have 3 problems..

The videos pretty much explain themselves but to add to those..
I have a scene with:
a fluid
some geometry
nparticles instancing objects shards!

Case 1:
Default quality renderer (Video 1), issue with instanced geometry When simulating or when panning around in the viewport there are some weird artefacts occurring which are the instanced geometries displaying incorrectly and in strange ways.. soooo:
I switch to HIGH QUALITY RENDERER and that problem is fixed!!


but then.....

Case 2:
The fluids appear transparent (Video 2). When directly in front of any geometry the fluids appear transparent.. ok... sooooooo:
I switch to VIEWPORT 2.0 aaaand PROBLEM FIXED

but then......

Case 3:
My instanced geometry and my nParticles disappear! (Video 3)
Video 3 also shows another example of 'Case 1' artefacts when toggling to default renderer!

Has anyone encountered those issues? Are there any explanations. Any advice on how the viewport renderers actually work?

Thanks in advanced!
