it's fixed upstream, untagging champagne, should be resolved before focal is out

This bug was fixed in the package mutter - 3.36.0-2ubuntu1

---------------
mutter (3.36.0-2ubuntu1) focal; urgency=medium

  * Merge with debian. Remaining changes:
    + debian/control:
      - Update VCS flags to point to ubuntu salsa branch
    + debian/gbp.conf: update branch to point to ubuntu/master
    + debian/patches/x11-Add-support-for-fractional-scaling-using-Randr.patch:
      - X11: Add support for fractional scaling using Randr
  * d/p/clutter-master-clock-default-Sync-timelines-to-hardware-v.patch:
    - Improves smoothness and reduce input-to-output latency
      levels (LP: #1862308)
  * debian/libmutter-6-0.symbols:
    - Update as per background mipmap levels patch symbol addition
  * Ubuntu bugs resolved since 3.35.91-1ubuntu1:
    - Higher than necessary CPU usage on mouse movement (LP: #1848951)
    - No mouse cursor drawn for radeon in Wayland sessions (LP: #1867080)
    - Restarting displays apps running on other workspaces (LP: #1819890)
    - Volume/brightness OSD make fullscreen video flicker (LP: #1828697)

mutter (3.36.0-2) experimental; urgency=medium

  * control: Build against gnome-desktop 3.36 and break old gnome-shell. So we
    get dependencies on libgnome-desktop-3-19. Otherwise we get two different
    versions of gnome-desktop loaded into GNOME Shell, which crashes. Break
    old gnome-shell for the inverse reason - it needs to be upgraded otherwise
    we get the mismatch the other way around.

mutter (3.36.0-1) experimental; urgency=medium

  * New upstream release
    + Fix placement of popup windows in multi-monitor setups
    + Fix invisible mouse cursor on some hardware
    + Updated translations

mutter (3.35.92-1) experimental; urgency=medium

  * New upstream release
    + Add side channel for starting required X11 services
    + Allow remote desktop services to inhibit animations
    + Avoid flicker when (un)redirecting windows
    + Fix clipping glitches in long text entries
    + Fix visibility of initially hidden windows
    + Implement scaled/transformed hardware cursors
    + Let BindConstraints update the preferred size
    + Make check-alive timeouts configurable
    + Make each stage view correspond to a single CRTC
    + Make Xwayland startup asynchronous
    + Ping windows on every window focus
    + Remove overhead from hot code paths
    + Support synchronized wayland popup moving
    + Update screen-cast code to PipeWire 0.3 API
    + Use DMA buffers for screencasting if possible
  * d/p/*: Rebase
  * rules: Disable remote-desktop temporarily. This now requires pipewire 0.3
    which is not packaged yet and needs to be worked on
  * control: Bump wayland-protocols dep to 1.19 per meson.build
  * debian/libmutter-6-0.symbols: Add new symbols for this release. One symbol
    which was introduced in .90 was dropped; -6's ABI is not stable yet.

Thanks fellas, it's fixed for me. Great release!

@Daniel this desktop version definitely appears quicker and smoother! No doubt due to your extensive work in that regard.
