Qubes Windows Tools Very Slow


Installed QWT on Windows 7 for Qubes 4.1 a couple days ago, with it running very slowly. Cursor skips constantly and video runs at very low frames. I’ve found the features stipulated in https://github.com/Qubes-Community/Contents/blob/master/docs/os/windows/windows-tools41.md work correctly, though bad audio stutters make sound unusable.

Dedicating more vcpus and memory does not seem to help. Windows 7 without QWT installed works fine.

I’ve also tried to uninstall QWT from the Qube, which ended up breaking it entirely. Not only does the Qube not start (regardless of debug), it has, according to the qvm-start dom0 command, deleted the memory block the Qube was dedicated to, too.

Not sure where to go from here, I appreciate any help.
