the machine up and plugged in the monitors I found the image had hung. As Juan mentioned, if I opened the image, moved it to the 5K, and immediately set it to full screen then it would hang. I didn’t get the same space is low message, but what we tracked down
was an allocation for the new screen that was failing.<o:p></o:p></span></p>

<p class="MsoNormal">Hi Folks,<br>
<br>
Yesterday Jon Raiford saved an image that did something similar to what you Mark describe when starting it, moving it to a 5k display, and setting it full screen. We spent several hours debugging together. The result is updates #6569 and #6570, pushed today
to GitHub. These updates do fix the issue as experienced by Jon. I'm pretty confident they'd fix what you Mark saw too.<br>
<br>
Thank you Jon for finding a case we could reproduce, and for debugging it together!<br>
<br>
Cheers,<br>
