Docker (or noVNC) runs too slow.

I discussed this a little with Shawn, but maybe an issue here would get some attention

One of my major gripes with Docker if we are planning on keeping it around is a huge difference in speed around GUI applications. This may be related to #13

This comes up in my rewrite of complx which has a more efficient instruction execution system. I'd rather not have to test this on 4 different platforms (Windows, Ubuntu, Mac, and Docker).

Program runs fine everywhere else, but docker runs at a snails pace.

I'll be willing to help out in whatever way, but I still am of the camp of no GUIs in docker.

I plan on starting work again around thanksgiving, at that time I'll see if I can get a code profiler to see what's causing the lag. I would assume that GUI events are what's causing lag.

If anyone wants to help I can also give instructions and pointers to where the complx2 binaries are.

Hey Brandon,
I'd be interested in maybe pursuing this for the fall semester (especially since I'd have the whole summer to work on updates to the image). I know Shawn definitely agrees with pulling GUI applications out of Docker and the whole VNC setup is very frustrating for both students and myself.

The big question is: are there any major outstanding issues with complx2/pyLC3 that would prevent us from moving to it (I'd probably want a full build to test with ~July)? If so, is there anything that I can particularly help with?

Hey, I hadn't been actively working on complx2, having some other issues I'm dealing with right now. Having this ready by fall is going to be a very tall order for me to fill, maybe next spring is doable.

Should mention IIRC all I have is the ability to load files and run instructions in complx2 currently. Nothing else. Most of the work I've done so far has been a complete overhaul of the codebase, adding more unit tests, and completely polishing the code on top on making it cross-platform.

I still have some outstanding bugs found the past two semesters to fix in complx. Then I have to port those fixes to the complx2 repo then I can start work again.

Last I remember I was debugging some weird segfault on the M2 mac I bought specifically for testing on macOS.
