I also use snipaste (free), but not that feature... well not until now
by any chance you using snipaste(pro)?
or any other tool?
because win10/11 explorer by default don't have that feature... well it will save to file if win+print screen (only full screen not zone)
fn+win+space (if keyboard don't have printscreen key)
snipaste (pro) actually features shortcut to save clipboard to file
as you can see free version (disabled)
hovering (i) ... not sure if related to the problem
yeh win snipping tool works just fine with OC...
snipaste sends screenshot to clipboard just like win snipping tool (you can check win clipboard history > needs to be enabled in settings)
but for whatever reason, saved file results in a black image... pasting on paint/email or any other program works fine .
