Apps only render on one monitor at a time

Hi, apps only seem to render on one monitor at a time. If I move them to another monitor, they stop rendering and stop responding entirely. As long as the app is 100% within the monitor it opens on, it works 100% - but if (for example) 10% of the app's window ends up on another monitor, that 10% will be all white and entirely unresponsive.

Here's a screenshot demonstrating the issue, this is one open Winboat app crossing into an additional monitor. Is there a fix for this? Or is this a limitation with Winboat/FreeRDP/Docker/etc?
