Thanks for the Update Richard. I think most people understand and I understand bugs and the like things happen. As long as we get some delicious cookies and maybe a backrub out of the dealio I think we can let it slide just this once XD. Nah keep up the good work I'm happy you guys are on it and I know it won't fix itself in a single day. Might be a week or three as things take time and ya'll have to make sure nothing else breaks with a fix.

We are still working on this issue right now as a priority.

Posting comments in all caps won't make it happen any faster. We understand your frustration, apologies that it's still causing you all problems.

Feel free to check back for updates, but please know that this page will be updated as soon as a fix is on the way.

I also seem to be forced to use the comments rather than the Response field at the top, as that is broken for me too and won't let me edit it :-(

Indeed this is a show stopper and not specific to VR as the OP title implies. I upgraded to 2018.3.2f1 and have this error spamming my console and killing my frame rate.

How did this get past QA let alone be unresolved for so long? I really hope this gets fixed very soon.
