Blender 2.81 Rendered display issues

Hi there,

I wonder if anybody else has this problem. I tried it with the latest build. In Rendered view I can not switch to transparent background and it renders the hdri even if the Transparent button is checked. The other thing is that rendered view doesnt refreshes if I change something (f.e. switch AO on or off or change some materials.). Wierd isn’t it?
