When viewing a file with Adobe Reader in the File Explorer preview pane, the file gets cut off if the DPI scaling level changes or if the File Explorer window is dragged between monitors with different DPI scaling levels. This is very annoying as it can make documents chopped off and/or hard to read. It seems to be an issue with Adobe Reader previewer not correctly/responding to scaling changes. As you can see in the image, the previewer is so cut off that you can't even see the controls or the scroll bar.
