Libre office Version: 6.4.7.2
Screen res 1920 x 1080
Fractional Scaling of screen display is 150% - scaled resolution 1280 x 720 (otherwise everything is too small for me to read at a normal working distance)
Now - The Clone Formatting cursor (paint bucket) is enormous compared to the mouse pointer and insertion-point size (which I have tried adjusting via Preferences / Mouse & Touchpad). Also, the size of the paint bucket is not related to the font size in use. I tried screen shotting but the tool image is not captured, sorry.
Where should I go to adjust this? Clone Formatting seems to be the only tool that is clumsy.
