Setting up Timeshift on a new Mint 22 Cinnamon computer changes the style and size of mouse pointer

[LinuxOnTheDesktop]

Describe the bug

Setting up Timeshift on a new Mint 22 Cinnamon computer the changes style and size of the mouse pointer. I had the new computer set to use 'DMZ-black' for the pointer theme, and at a reasonable size; that worked; but when I put the pointer over a Timeshift window, the pointer becomes the new-default curved pointer, and huge. When I move the pointer out of the Timeshift window, the pointer returns to normal.

To Reproduce

1. Install new copy of Mint.
2. Set mouse theme to DMZ-black and, perhaps, enlarge the pointer a little.
3. Open Timeshift and put the mouse pointer over it.
4. Witness the weirdness described in my first section.

Frequency: thus far, always - closing Timeshift and re-opening it does not remove the problem.

Expected behavior

Obviously, not 4.

Screenshots

In both photos, the banding is an artefact of my camera (or lack of photographic skills). I do not have the new PC sufficiently setup so as to do proper screenshots (or at least not to upload them easily to here).

System:

• Linux Distribution Name and Version: Mint 22
• Desktop: Cinnamon
• Application version: 24.06.3-wilma
• Computer: Framework AMD 13

I find that in the Synaptic package installer there is a similar em-bigification - and I seem to remember that problem from deep in the past . .

I have found a solution - though on a fresh install the problem should not appear in the first place.

The solution is as follows.

$ sudo update-alternatives --config x-cursor-theme

One is then given a list of options to choose among. One should choose the option that matches one's Cinnamon pointer theme.
