Flameshot disappears from taskbar

Seems every time I actually want to take a specialised screenshot I have to reload Flameshot - perhaps there's a better screenshot tool, like ShareX on Windows which can "natively" take over the `prt sc` button.

The issue mentions Flameshot and the taskbar but names no files, tests, or entry points. Start by reproducing the disappearance when taking a specialised screenshot and determine whether the expected outcome is fixing Flameshot's taskbar behavior or choosing another screenshot tool; done should be defined before implementation.
