Bug Description
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.
What Could Go Wrong
-------------------
See the master mutter 42.9 bug LP: #1998286
Original Bug Report
-------------------
Just to report an issue that other people have reported to GNOME and in Reddit, that seems to also affect Ubuntu 22.04.
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.
