many functions are too slow
When you are moving through the user list for example by clicking tab to select the correct user you are responding to, it takes way too long for that text to be input into the input box and to allow typing. It is a very visible 2 section delay.
I am running AMD Threadripper with 32gigs of ram and PopOS 19.04. This is only one example many others exist.
For example, switching rooms is nice and clean and fades in and out, it looks nice, but it seems to lag and is visibly slow.
I am sure I can mention more, but I just thought I was submit my observations.
