MCL-14872Minecraft Launcher seems to have a memory leak
When I launch 1.16.1 and play for a while, my system starts having memory issues. When I check, the launcher, which is still running in the background has started consuming all available memory and often causes my system to thrash if I don't catch it in time and kill the launcher process.
This is on Linux (Ubuntu 18.04) and has happened for the two versions of the launcher i have used. the prior version (updated to make sure it wasn't already fixed) I had been using with 1.15 I believe since it came out. It did not happen before I started playing on servers running 1.16.
Environment
Ubuntu Linux 18.04 with 24g system ram
Launcher installed as Debian package from Mojang site. Launcher options are not set to keep launcher open while games are running nor open output log when games start.

I just watched the system monitor and the launcher was jumping by about 2K every couple of seconds. If you need, I can record it and attach it.
Hi there!
Could you answer few questions regarding this issue, it will help with the investigation:
This ticket will automatically reopen when you reply.
1: I have not tried the newest version of the launcher but I did try it on the lasest version of 1.16 (since you cannot play a 1.16 server with a 1.17 launcher, that's not a valid concern, nor can I test it since I cannot connect to a 1.16 server).
2: Yes, I've tried multiple sources for the launcher (since it's a Linux system, both the default distro install and a straight download install, they utilized different directory destinations).
3: I do not have any of that software installed that I am aware of (meaning I don't even recognize the majority of it, I presume it is windows based software and as I mentioned in my original report, this is a LINUX box, there is nothing windows on it.
4: how much more in depth do you need me to get? I launch the client, connect to the server and monitor the system monitor that shows memory usage.
5: I can, it will take a bit of time as I am quite busy with 2 new clients for work and don't have time to play right now.
