This appears to be a bug in WindowFX 6.05 regarding how it acts in Windows 10. Hovering over the taskbar thumbnails does not show the window contents.
- Turn on WindowFX Minimize animations (non-Default animations)
- Minimize a program window. If it doesn't show the expected animation, restore the window and minimize it again, or use another program window.
- Hover (don't click) over that program's taskbar icon until the thumbnail appears.
- Hover (don't click) over the thumbnail.
Expected behavior: The preview window, though still minimized, should appear on the desktop for as long as you're hovering over the thumbnail, with all other windows temporarily hidden.
Actual behavior: All windows temporarily hide, but the window does not appear on the desktop. It stays invisible.
