Zoom and Anaconda Navigator have weird scaling

I recently installed Zoom and it is opening up really weird - everything is super zoomed-in. Is there a way to change the resolution of a program? I was wondering if there was a configuration file that zoom was getting its settings from and maybe that file had the resolution incorrect.

By the way, I have already tried sudo apt purge ... to uninstall it and then manually removed the ~/.zoom directory, too, but that did not work.

Edit 1 [Included System Settings]

Screen Resolution: 1920 x 1080

OS: Ubuntu 20.04 LTS

GNOME Version: 3.36.2

Windowing System: X11

Edit 2 [Installed Anaconda and it is doing the same]

I just installed Anaconda and opened up Anaconda Navigator, and this is how it's being displayed:

Other programs, like File Manager, Chrome, LibreOffice, etc. are displaying okay.

Solution 1:

Fixing Zoom's Scaling Issue: Check out u/190's reddit post.

TL;DR of the post: Apparently, Zoom started doing that after some recent update. To fix things, you just have to set autoScale to false in Zoom's config file, which is ~/.config/zoomus.conf.

Fixing Anaconda Navigator's Scaling Issue: Turns out my Anaconda Navigator was not displaying right because it was configured by default to automatically scale up on high DPI displays, and when I disabled that option things went back to normal. Here are the steps you can follow to disable it:

1. Run QT_SCALE_FACTOR=0.5 anaconda-navigator to open Anaconda Navigator. (If you run anaconda-navigator without a QT_SCALE_FACTOR, it might run too zoomed-in for you to follow the steps below)

2. Go to File > Preferences, and uncheck "Enable High DPI Scaling".

3. Close Anaconda Navigator.

Solution 2:

Fix for anaconda-navigator scaling issue.

If the preferences window was too big to save/apply the changes using the GUI.

Then, follow the following steps:

1. open preference file sudo nano ~/.anaconda/navigator/anaconda-navigator.ini
2. update enable_high_dpi_scaling = False
3. restart anaconda-navigator

Hope this will solve the issue.

EDIT: As per Sublimer's comment for some users, changing enable_high_dpi_scaling = None works.
