A Player is configured such that is is spanning across 5 screens - each of which is its own small video wall.

There is then a region defined grouping those in to blocks of 2 screens, 1 screen, 2 screens.

Layouts are then run using that region setup, with multiple images in each region.

The layout runs as expected, but occasionally one region is missing and the background colour or image is shown. No errors appear to be logged in this case - the content is simply missing. The Player will normally recover by itself.

It's not always the same region, but it tends to be the first or last. Windows updates and graphics drivers all up to date. When in that state I can open the info screen on to the place where the missing content should be, so the screen itself is functioning as expected.
