indiPDF is a comprehensive PDF editing application designed specifically for Linux.
It provides all the tools you need to view, annotate, edit, and manage PDF documents
with a native GTK-styled interface that integrates seamlessly with your desktop.
Features include:
indiPDF respects your privacy and works entirely offline. Your documents never
leave your computer.
It may not be just the Flatpak. I got the system package and in Mint 22.3 Cinnamon I'm also getting a white window. Says indiPDF in the title bar but nothing else loads. Sounds excellent, though! Looking forward to either a fix, or to figuring out what I'm doing wrong. :) You can Ctrl-O and get the appropriate dialog box, so something's working under the hood, but when I select a PDF nothing seems to happen.
Appears that it does not come with everything required in the Flatpak, it starts but the window is white and blank.
