Flickering Frames (For visual-impaired?)

Customization
1

Hey.
I have installed Zorin OS 18.1 and made some changes in appearance. Since then frames flicker (as dialog boxes etc.) when changing focus.
I guess it was something for visual-impared but cannot find it to stop doing the stuff.
Any idea, please?
Thank you

Hello and welcome,
run this in terminal

echo $XDG_SESSION_TYPE

If you are in Wayland, switch to Xorg:

  • Logout
  • At the login screen, click your username (don't enter password)
  • Click the gear icon in the bottom right
  • Select "Zorin Desktop on Xorg"
  • Log in

Do you have maybe enabled the effect "Jelly mode"? In the app "Zorin appearance" you can disable it.

Do you have installed third-party gnome extensions? If yes, please disable them and test then.

I will. But I am a newbie on Linux. How do I know what third-party gnome extensions did I installed or could safely disable?

You would know if you had installed third-party extensions. Usually, you use the Extension Manager

sudo apt install gnome-shell-extension-manager

to install GNOME extensions, and when you open it, you'll see all installed GNOME extensions in the "Installed" tab, and you'll also be able to see whether they're enabled or disabled. There is no risk to disable all user-installed gnome extensions (you don't need to remove them, just turn off the slider if you have user-installed extensions. Keep the system extensions enabled which are enabled).

I have checked it in Extension Manager and it says: There are no user extensions installed. Only thing I could do is disable rest of the extensions but probably I should not

No, don't do that, keep them. They are needed to have a taskbar and the start menu and other things. Usually they don't cause flickering.

Do you remember what you have changed when the issue with the flickering appeared? Do you have an Nvidia graphics card?

Do you have fractional scaling enabled? If yes, test it with disabled fractional scaling.

What is your system ? brand and model ?
GPU ?

12

Nope. I do not have fractional scaling enabled.

Do not think so

So you go back to Wayland ?

Yes, since it does not change anything. Or?
