Can you elaborate? I have been using GreenShot for ages now and haven't had a single issue with it. It works perfectly well on my 4K monitor. What issues are you experiencing?
The UI is tiny. I'm on Windows 11, which I'm sure is the issue.
Ah, makes sense. I rolled back to Windows 10. 11 is too scary for me.
Have you given ShareX a try? Also open source, but maintained, unlike Greenshot.
