In my Windows Display settings, my external monitor's "Scale" is set to "150% (Recommended)" and my laptop's internal display is set to "250% (Recommended)". > I'm on Windows 11 and have taken about 10 screenshots trying to reproduce unsuccessfully. > > If you took 10 screenshots, about how many would have the black lines? 10 out of 10. I thought the bug was intermittent before, but I think the bug happens reliably if the screenshot is wide enough, regardless of its height. For example, I was unable to reproduce on my laptop's internal display with scale "150% (Recommended)", but I _was_ able to reproduce after when I changed scale to "250%". Today, the lines in my screenshots are always at the same X position, regardless of the width of my screenshot (as long as the screenshot is wide enough). However, today's X position is different from the X positions in my original screenshot.
