16 Bit nodes with 16 bit inputs outputting 8 bit results intermittently

In the latest build (12.2.0 Build 5912) I am having issues of nodes that are 16-Bit with 16Bit inputs output 8-Bit results randomly.
(Windows 10) 
No noticed node in particular, have confirmed with Blend node, Slpoe Blur and Non- Uniform blur. However it is not consistent - When I notice it has happened, I can copy the node and find that the copy works fine (shown in attached example).
I have been working mostly in 4k.

I went to test 2k to see if the issue still occured, and found that after changing to 2k, some nodes are not updating resolution either - example attached.

Please advise if there is a fix / if other info etc required.
Thanks!

Stan Brown

            And in the meantime, we found a fix yesterday 🙂

            The new version with the fix should be online end of next week. Thanks in advance for your patience.

              @Luca Giarrizzo Thanks.

              I can confirm that the workaround does appear to work here.

                Hello,

                 

                Thank you @davescm for the heads-up!

                 

                Indeed, there is a known issue related to the propagation of inherited parameters – e.g., Output Size, Output Format, ... – in the 12.2.0 version. We are working on a fix.

                 

                In the meantime, you may try to enable In-Context Editing as a workaround. You can find the option in Edit > Preferences > Graph. I appreciate your patience while we resolve this!

                 

                Best regards.

                  Hi

                  I can replicate this. There appears to be issues with the inheritance of both size and bit depth.  At first I suspected it was on node trees not connected to an output, however that proved not to be the case, the issue still occurs with all node trees connected to outputs.

                   

                  System : Windows 10 v21H2 : CPU i9-10920X; 512GB RAM : GPU RTX3090 Studio driver 472.84    SD version 12.2.0 build 5912

                   

                  I will tag Adobe's @Luca Giarrizzo to see if he can help
