OK. What if we choose a wallpaper, run it through Qubes’s Trusted PDF converter and then use it?
I would argue that this is actually more secure than using default KDE since we are actively looking at this attack vector instead of relying on others do it for us.

Does it actually work for our use case?
Convert jpeg’s / png’s to what? To bmp?
WhonixQubes could answer that best.
I’ve haven’t used the Qubes Trusted PDF Converter yet, so don’t know much about it.
Very briefly scanned this post on it:
Could be wrong on conclusions here:
Looks like it converts PDFs into RGB pixel representations (removes text) and makes a simple/dumb/flat image based PDF file.
Also mentions this about images:
The converter can also be used to convert essentially any image file, such as JPEG, PNG, etc, into a PDF, using the same method.
So maybe it would be useful in your process of filtering an image…
IMG → TRUSTED PDF → IMG
Assuming there was a trusted way to convert the trusted pdf back to an image.
What is the advantage of using the Trusted PDF tool over just doing a screenshot from dom0? Do you hope to preserve higher resolution that way?
