[Cinnamon] Intermittent: window judders in Themes -> Settings

[LinuxOnTheDesktop]

Describe the bug
The window at Settings -> Themes - Settings occasionally resizes itself suddently and seemingly at random.

To Reproduce

1. Boot live ISO.
2. Set themes as follows: icons, controls and desktop - all Mint-Y-Dark. (This step might be unnecessary.) Close all settings windows.
3. Settings -> Themes - Settings.
4. Move the pointer to (or just below)? - the 'Lorem ipsum' text.
5. See the settings window judder, in that suddently it resizes itself horizontally (and stays resized). Or at least that happened once. I rebooted, tried and failed to reproduce the problem. Yet: clicking between the tabs of Settings -> Themes did yield the same judder - once. I closed the window, reopened it and . . no judder.

Expected behavior
No judder, ever. Resizing the window immediately upon changing tabs is one thing - but not what is happening (intermittently) here. Rather, the effect kicks in after a delay (or/because pointer movement triggers the problem?).

Screenshots

I am afraid I have no screenshots or video.

• Is your system all up-to-date?

Yes and no: I have installed all updates, but - because I am on a live USB (which will not retain the updates, right?) I have not rebooted. I did restart Cinnamon.

[LinuxOnTheDesktop]

Closing, because just now I experienced something similar on Mint 20.3. The effect in the live session was more pronounced than on 20.3, but that difference might owe to live sessions being slow. There is something not right here, but it does not seem to be a regression.
