This doesn't happen all the time and haven't found a way to replicate it reliably.

But my render window stops working about half the time after returning to Live environment after editing a device.

Only way I've found to reactivate it is to reload my Live Project.

Ironically bug reporting snapshot doesnt seem to be working - probably my mistake though

Hello,
I'm not able to reproduce this. Could you attach the device you are testing with so I can give it a look? Is your qmetro set up to be manually turned on or is it being automatically activated?
Any further steps you can give to help us reproduce and isolate the issue would be great.
Also, please send along your system details, OS, etc.

Best,
Andrew B.

Sorry - didn't spot this before and problem seems to have gone now.

I think it was maybe because I had two jitter gl windows with the same name in a patch?

Either that or copying devices into a new live set fixed it.

Not terribly useful beta testing that.
