Screen blacks out when mouse turns to a custom shape

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:

  1. I opened a document I needed to sign.
  2. Menu options: Objects → Place Initials → Create New Initials
  3. Change “How would like to create your initials?” to “Select signature image”
  4. Click the “…” button
  5. Select a PNG file.
  6. Click “OK”
  7. 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.
