How to increase cursor size in 7.2 beta 2, Linux Mint 19.3 w HiDPI setting

[gkalexh]

Hi!
New to DigiKam. Very impressed. Thanks for marvelous product.

Using .appimage.
Using Mint 19.3 cinnamon desktop. Dual 4K monitors.
I've set HiDPI settings in settings > Configure digikam > Misc >system tab.

Haven't found a place to adjust Cursor size.
FWIW, my cursor is about the height of a capital letter in the Misc settings menu.

Any thoughts?
Thanks so much!
