Created attachment 106250 [details] Setup with overlap I'm using three monitors, but it's reproducible only with two. When I rotate one monitor, all monitors to that monitor's right will show a sliver of their neighbor to the left (rotated or not). This sliver does not show up on screenshots. I've had it for a long time now, but it got annoying when my right-most monitor is a TV and when the screen is black, a bright distracting sliver of its left-neighbor shows up. When I arrange the rotated monitor so that it's in the middle, for instance, it's left-neighbor is not affected, so only monitors to the right of the rotated monitor seem affected. I'm attaching screenshots of the monitor configurations coupled with pictures of what it actually looks like. The image with a rotated screen shows a picture of the overlap of the left-most monitor, which is rotated, onto the middle monitor. It also shows the overlap of the middle-most monitor onto the right-most (the TV). The image without a rotated monitor just shows that there's no overlap. Please let me know if there are any logs or other info I should post to help diagnose this! PS: I'm on debian stretch, which just turned stable.
