WSL Issue

[Daniel Boyd]

I am developing apps for my work in Windows Subsystem for Linux. My company
is a Windows shop and I prefer developing using clang/libobjc2, so WSL has
provided a good fit for me. 

On my main development machine, things mostly work well, though there is an
occasional graphics glitch that seems to occur most often when I launch Gorm
by double-clicking an interface file in ProjectCenter. About half the time,
the two applications start flickering for a minute or two until eventually
things calm down and start working.

I just deployed a new laptop for a user this week and the flickering problem
on this machine is much worse. I can't run any applications at all. They
just flicker continually and I am forced to force quit them from the task
manager. I think the issue may be related to the fact that I am technically
running these through a remote X11 session. Every time I launch an
application via WSL, I get the following messages on the console:

Xlib:  extension "MIT-SHM" missing on display "localhost:0".

I traced this message to a source file in libs-back--XGServerWindow.m. I
suspect my problem has to do with the fact that I'm running X remotely and
also rootless. If I run X with the root window showing, the flickering
doesn't happen. I think the library isn't able to determine the geometry of
the screen and then freaks out. Anyway, any help would be much appreciated.
The user I am deploying this laptop to uses several of the GNUstep apps I've
written and none of them run at all at the moment. I am running the latest
versions of all the GNUstep libraries from github.
