Hi guys,
MightyKeb is right in that the chat icon disappearing is notoriously difficult to fix as we are still investigating what is causing that problem in the UI. We have, however, fixed a number of other issues mentioned like the low frame rate and performance issues (these were linked to some memory leaks.) I know its not the complete list of fixes you were perhaps expecting but we are definitely crossing them off as fast as we are able to. Thanks again for reaching out to the feedback line on this stuff, the wealth of info really helps!
