I've updated most of my desktops to Ubuntu Mate 20.04, but have hit a wall on upgrading my two work machines still running 18.04. Both of my work machines require a lot of remote desktop usage with VNC and I haven't been able to make Ubuntu Mate 20.04 work fast enough.
The issue comes down to the selected window manager. Marco (Adaptive compositor) works great for my local desktop, but is very slow for VNC remote desktop. In 18.04, Marco (No compositor) works fine, but in 20.04, there are some windows I'm not able to resize (like mate terminal.)
The most probably cause is that the theme I'm using, Adapta, hasn't been updated for the latest version of Mate, but works fine with Marco (Adaptive compositor) because of Mate's new magic. If I chose one of the included themes, it does work well enough (it's still hard to grab windows for resizing, but I don't think it's much worse than 18.04), but I like Adapta. So, my questions are:
- Does anyone know what part of a theme needs to be adjusted to resolve the issue of not being able to resize a window?
- The enhancements made to 20.04 for resizing windows no matter the theme is wonderful. Is it possible to port that behavior to Marco (No compositor?)
- Any work around to make Marco (Adaptive compositor) fast over VNC?
Even if you don't have an answer, thank you for taking the time to read my question.
