I believe Cassowary (https://github.com/casualsnek/cassowary) is an older tool that does pretty much this.

My experience with it is that FreeRDP in rootless mode isn't very good for Windows applications that do anything special with window borders. Using Office and many other programs became a pain.

When it worked, it worked really well, though. Reminds me of the same feature that VMWare used to offer many years ago for running XP/Vista programs on Windows 7 through a VM.

can you do "pass a single window" with freeRDP? I haven't actually seen that before so forgive me for asking.

This project looks like it does that, but I could be wrong.

Yes, it's rootless mode. FreeRDP only works with X11, so it runs in Xwayland and the integration isn't as smooth as it could be.

It's reminiscent of rootless mode in Parallels, just as janky, too.

This is incorrect. FreeRDP has supported Wayland since a long time via their `wlfreerdp` client - which is now deprecated, Wayland support is now available via their `sdl3-freerdp` client. The SDL client was alpha quality a couple of years ago, but as of the last couple of recent releases, it's been pretty decent. I'm unsure though if its reached full feature parity yet with the X11 client.

Thanks for pointing this out, you have just made my life easier

Spoke a little too soon, can't seem to get rootless mode working with sdl-freerdp3 in the latest kwin_wayland, but desktop mode works

That's what "rootless" mode does.
