** Description changed:
- Just to report an issue that other people have reported to GNOME and in
- Reddit, that seems to also affect Ubuntu 22.04.
+ Impact
+ ------
+ Mutter 42.9 includes a fix for tiled window resizing. Before the fix, window
resizing could use very large amounts of memory and be laggy.
+
+ Test Case
+ ---------
+ 0. Install the updated mutter packages. Log out then log back in.
+ 1. Open System Monitor. Tile it to the Left.
+ 2. Open a Terminal. Tile it to the right.
+ 3. Click the Resources tab in System Monitor.
+ 3. Right-click the System Monitor in the headerbar and click Resize.
+ 4. Move your mouse left and right to resize the window.
+ 5. The memory should not dramatically spike higher as seen in the System
Monitor's Resources tab.

If you snap 2 windows side-by-side in Wayland and then try to resize
them, it's very slow and uses a lot of memory.
