- Modern DX and old Direct Draw games often was a clusterfuck in order to keep them running fast in Windows 8 and up.

- XVideo and overlay video for Windows were 100% the same; green glitches on drawing, blue screens on screnshots et all.

- Same issue in Windows with pixmaps.

- RDP was fine there, even Gnome adopted it. But I prefer 9front's transparency, you don't need to get everything from the host to use it, with 9front you can just get the device you want, you can decouple auth from the GUI and a lot more, even the network and audio devices. Much fetter than X11's remote setups, VNC, RDP and whatnot.
