That's another bug. I tried to save with a selection, and yes, the Histogram fails on the next load, until the marquee is deselected. But that's not a serious problem though. What I'm experienced is that I cannot see the Histogram of a certain marquee selection. However I try, it just doesn't work. This time I tried to save with or without a marquee selection, and with or without the "Marquee" option selected, the problem remains. Also, I converted the document into RGB 8, the problem remains, I will attach the .afphoto file here. The first video is when I try to save with or without a marquee selection. The second video is when I convert it into RGB 8. save_with_selection.mp4 convert_to_rgb.mp4 bug_reproduce_RGB.afphoto

In fact, in my Affinity Photo, RGB file also have this problem. (I first found this problem in a RGB picture, then I created another file to capture a video.) I don't see complaints about this problem on the forum. Although it seems to make no sense, but are there differences between versions, and could it because the Chinese version or Microsoft store version?

I cannot use the option "Marquee" to show the histogram of the pixel selection. This happens every time in every file. It seems when there is a selection, histogram freezes, even if I selected "Layer" option instead of "Marquee". I've recorded a video and also uploaded the .afphoto file in the video. I'm using Windows 10 Home, x64, version 18363, and the latest version of Affinity Photo in Microsoft Store 1.8.3.641 downloaded yesterday. affinity_photo_bug.mp4 bug_reproduce.afphoto
