Some image nodes send Window Property information down stream like the “Make Text Image” however that information can sometimes override the nodes connected the the “Set Windows Properties” port. Is there a way to ensure that these values are not overridden?
Confirmed; something fishy is going on there — after you’ve used Change Window Size, changing the window’s image should not cause the window to resize. I converted this to a bug report; I’ll try to get that fixed in the upcoming Vuo 1.1 release.
In the meantime, you can replace Render Image to Window with Render Layers to Window or Render Scene to Window — the latter 2 nodes do not automatically resize themselves.
