Screen blacks out when mouse turns to a custom shape.
Behavior only showed while using Gnome/Wayland, Gnome/X11 it was fine.
The software I used was “Master PDF Editor 5” (From Flathub)…
Steps I took:
- I opened a document I needed to sign.
- Menu options: Objects → Place Initials → Create New Initials
- Change “How would like to create your initials?” to “Select signature image”
- Click the “…” button
- Select a PNG file.
- Click “OK”
- Menu options: Objects → Place Initials → [the png thumbnail you just added]
This changes the mouse cursor to the shape of the signature/png, and my screens just black out entirely.
