Quote:Indeed, I have no bug feedback. How do I view the screenshot?when you start the UV window and get that "A window opens with internal error?", please use the option for the whole screen capture (PRTSC) as shown in the following article: Methods to take screenshots on Ubuntu 22.04 LTS
I ask for it because we need a tip about what can be happening from your side.
I work on Windows, but I have a Ubuntu 22.04 partition which I can't experience the problem you are reporting.
Are you using Wings3D natively on linux or via Flatpak?
