Colored border doesn't work on second monitor

[Special]

Hi, using latest Sandboxie v4.16, (paid if that matters) and have noticed that when fullscreen applications are ran on a second monitor the colored border (usually yellow by default) does not display, on the primary monitor this works fine.

As a temporary fix I've found that dragging the sandboxed window around a bit moving it slightly off from center will cause the border to display.

On primary monitor it works great.

Secondary not so great.

Moving it some will bring it back.

Shrinking the window size also brings it back.
