An android phone jpeg should work. This is one in Gimp 2.10.32 / Mint 21
Before anything else, check the obvious. Tool options here detached to see all settings
(1) The brush. Use a suitable brush, make sure it is not the (empty) clipboard brush.
(2) Mode Normal / Opacity 100
(3) Tool size large enough to show
(4) Dynamics off
(5) Alignment usually None / Aligned / Fixed
(6) Unless using registered alignment (clones from layer to layer or image to image) make sure you are on a visible layer.
Otherwise to reset everything to defaults: Edit -> Preferences -> Tool Options then Reset Saved Tool Options to Default Values Restart Gimp That should also fix dodge/burn
You can always post your own screenshot and someone might spot something.
No, it will not affect the clone tool, however depending on Mint and Gimp versions the support for associated python 'heal' plugins is not there. Which version Mint? (20 and not updated ?) and Gimp version 2.10.?? (from PPA / repo / Flatpak / Appimage)

Quote:I also previously installed the resynthesiser plugin - could this be linked?
