Any updates on this issue? I have four monitors with the following resolutions/DPI: 50" @3840x2160/150%DPI (main monitory), 2x27"@1920x1080/100%DPI, 34"@2560x1080/100%DPI. I'm attaching a screenshot that shows one of the many issues induced by having the 4K set at 150% DPI (or anything other than 100% DPI, for that matter). Love Displayfusion but the taskbar replacement is mostly unusable due to not properly handling multi-monitor, multi-DPI scaling situations.

The issue in screenshot is on left hand monitor where the Windows Start menu shows up near the top of the monitor and about half of the menu is not visible. The Windows Start menu displays improperly on all but the main monitor.
