I did more thorough tests today and the issue is very likely out of display area image data.
Couldn’t find out what would be the actual reason and that probably needs a developer to take a look, but it can be confirmed to be related to outside of display area pixels. If Crop is added just before Transform, then it works fine. I have tested it in Nate’s comp as well as with newly created similar setup.
Also without crop, if transform is inverted in Transform node options playback works fine, but I have no clue how that changes the situation as big part of image data is still out of visible frame.
I included my test file here as well for others to test and confirm with Nate’s file.
