App indicator icons too small after update to Ubuntu 20.04

After updating to Ubuntu 20.04, app indicators became very small, and now when an app like Telegram has notifications, they are just overlapping the whole icon. Is there a way to adjust this manually?

Screenshot 1 - Smaller icon:

Notice how the Telegram icon (blue circle with white paper flyer) is smaller than the two icons next to it (Slack on the right).

Screenshot 2 - Clipped and deformed:

Notice the Telegram icon (grey circle with the nubmer "2" in it). Firstly it's clipped; the top and left side of he circle are not shown. Secondly, the grey circle is in fact a badge that is supposed to be placed so it only partially covers the normal blue Telegram icon (similar to the inbox icon shown in the browser on the screenshot); instead it's scaled to take up all the space:

If you would like to modify the size of the status bar indicators (or other settings such as padding), you can do so with the Just Perfection extension (https://extensions.gnome.org/extension/3843/just-perfection/). (Note that you cannot do this on an app-by-app basis. However, you might take a look at the settings to see if there is anything helpful in there.
