  Various bugs/issues in Linux Ubuntu 24.04 accessibility checkboxes
  glitches, second unknown display, lagging, problems with mouse cursor

Bug description:
  Dear Sir/Madam

  Could I report several bugs that I have encountered during the usage of Linux Ubuntu 24.04 on HP desktop PC?
  The affected package is probably Gnome and also Linux Ubuntu 24.04 installer.
  I can provide more information if necessary.
  Sorry if some of these bugs have already been reported.

  - during the installation of Linux Ubuntu 24.04 in accessibility settings, when I clicked zoom functionality then 2 mouse pointers were visible, 1 bigger and 1 smaller synchronized with each other.
  - when I checked checkbox zoom on and off several times then the installation process of Linux Ubuntu 24.04 got hung and I needed to restart it

  After the successful installation of Linux Ubuntu 24.04 I encountered some other issues
  - some problems with accessibility settings. Some problems with Large Text and High Contrast checkboxes. Switching Large Text checkbox doesn't change text size. Also can't unpin accessibility logo permanently from top-right corner of the screen. Some problems with checkboxes of Large Text, High Contrast, some kind of glitches/unsynchronized checkboxes between top-right corner accessibility panel and gnome-control-center. Maybe these problems were caused because I checked these accessibility checkboxes during the installation.

  - mouse cursor lagging every 1 second for a period 1 second.
  - cursor hovering/clicking in a wrong place like it was displaced several pixels away from a mouse cursor image, especially noticeable in nautilus file browser or when opening files in gnome text editor
  - generally often some lagging like delayed start of many applications like terminal or during switching between windows
  - after switching to another window with mouse click then it occasionally freezes (clicking anywhere on it has no effects) until I press alt + tab keys combination

  - in settings in displays panel, there is visible second unknown
  display even when I am only using 1 monitor now an only 1 video cable
  is attached to my computer. I attached screenshots of this situation.

  - nautilus file browser application vanished out of nowhere without
  notification, and I need to install it again

  - switching mouse cursor type to other than Yaru and Adwaita freezes Linux with a white screen but this has been reported as far as I know here, and there is an easy fix for this issue
