V2.8 render issues

Many scenes of the Blender Institute-prepared benchmark pack fail to render with the latest Blender v2.8, the v2.79 master build has no such issue. Additionally, I also tested some older splash screens as well.

bmw27 and fishy cat - OK
splash v2.77, splash v2.78, koro, pavilion barcelona - no render output from command line, when GUI is used, it renders the tiles but the final image disappears at the last moment
classroom - fails to load chairs, lamps, etc. but has render output

Both CPU only and CUDA rendering produce the issue. Tested on Win10 extensively with CPU, but had a look on Ubuntu as well and the same occurs.

There are some new errors in the log file as well.
koro - multiple dependency cycle detected
blenderman - Error: Not freed memory blocks: 2, total unfreed memory

CPU: AMD Ryzen 7 2700X
OS: Microsoft Windows 10 (10.0) Home 64-bit - Version 1809/RS5 (17763.134)
SW: blender-2.79.0-git.33750e8abba-windows64
SW: blender-2.80.0-git.9abcf56fa88-windows64

Can anyone have a look? Thank you!

do not worry about it, i also meet these issues, blender is at alpha stage currently.

According to the latest blog spot v2.8 veta should be out in any days.

We are currently an estimated 2-3 weeks away from releasing a 2.80 Beta version, which will have all the main features that will be in the 2.80 stable release.

I thought these kind of issues will be ironed out for the beta.

Reported the issue on the bug tracker.
