Issue starting zoom on Ubuntu Mate 20.04




I have an issue where after installing zoom on my Ubuntu Mate 20.04 (running copiz), I see zoom running in the taskbar but the main window is about 10x10 pixels. I can not resize. I did try to delete ~/.zoom folder and restart. Same issue.


I installed zoom using both ways. I did uninstall the previous version first before installing the next version.

1. Downloaded deb file from zoom website and installed it 

   $ sudo dpkg -i zoom-version.deb

2. Installed it using flatpack


Does anyone knows what might be the issue. I did try to chat with support but the bot is too horrible to understand that I need to chat with people so I can provide any logs they might ned to resolve this issue.


$ flatpak info us.zoom.Zoom

I am staying on the flatpack version for now.


Please let me know if there are any logs or any information I can provide or how can I contact developers/support. 


EDIT: Btw suggested library "


is not available on Ubuntu 20.04.  But I see libgstreamer-plugins-base1.0-0



Any anyone from Zoom support can chime on this? Any information I can provide?


Hi @Guma, thank you for using the Zoom Community to seek support. I see you have not yet received a response from the community… I apologize for the delay! I appreciate your patience.


Hang tight while I try to find some subject matter experts to take a look at your question and provide you with support 🤓.

Thank you, 

Zoom on my system is totally not usable. I did try uninstalling, removing coding files, reinstalling. Nothing helps. I am running zoom version 5.7.31792.0820 from flatpack.


After starting zoom I see it in tack bar, but the window itself is very very small and I can not resize it. Please see attached screenshot where red arrow is pointing to zoom main window. 

Please see attached screenshot. If that makes any difference I am running a very wide monitor at a desktop resolution 5120x1440 resolution with Compiz enabled.
