I have a problem with my 1080p and 4K screens. Depending on the layout in the display settings, blurring fences will only work on half my 4K monitor. If I place my 1080p monitor somewhere on the right of my 4K monitor, the problem does not happen. The thing is, my 1080p monitor is physically on the left of my 4K, so it's not a solution.

^ The right side is not blurred at all

^ The bottom is not blurred

^ It does not happen when the 1080p monitor is on the right half of the 4K monitor

^ It does not happen when the 1080p monitor is on the right half of the 4K monitor
