In the FOSS tutorial; https://itsfoss.com/flameshot/, at 1.00 mark, when the option box is open, there is an option to adjust the active thickness, rather than using the mouse scroll. I do not have that option. How do I get that option?
Which version of Flameshot are you using? Mine is 0.6 and the thickness option is present in it.
Hmm… that’s the same as me. But I fail to see why you don’t see this option at all.
You can try downloading the deb file to install the latest version from its GitHub releases page to see if it makes a difference.
