Hi,
thanks for testing this, I believe most of problems should be fixed in B1 RC2.
Relevant bugs that were fixed in last few builds:
- custom bokeh shape not correctly oriented
- modifying custom bokeh shape in render settings can cause crash
- bokeh changes not correctly updated in IR
- bokeh settings on camera was ignored
- in IR, custom shape set in render settings was not used at all
If you find some problem with DOF that is not fixed yet, please let me know.
