macOS: Display resolution low after sleep mode or disconnecting external display

Hi,
sometimes, when I leave Anki open and put my computer in sleep mode the resolution of Anki is very poor. I have to quit Anki and reopen it so get back to the normal resolution.
I can observe this issue also when I have Anki on an external display and disconnecting it. Anki will then have a very poor resolution in my internal screen. When connecting again an external display Anki has still a poor resolution. Only a restart helps.

Any Ideas what is causing this?

I’am using the latest version of Anki (Version 2.1.33 (3f403040) and macOS 10.15.6 (19G2021)). I work on a MacBook Pro with an external display (2560px x 1440px).

Steps to reproduce:

  1. Connect external display,
  2. Open Anki with window on external display
  3. Disconnect display :arrow_right: resolution will be poor
  4. Reconnect display :arrow_right: resolution is still poor

I’m afraid this is an issue with the toolkit Anki is built on, and we need to wait for them to fix it.

Ok, thank you very much for the information.
Which toolkit is Anki built on?
