I have the apps Notepad++ and PDF x-change editor in the same bottle, made with the Apps template. In Flatseal, I gave Bottles permissions on my /home and some other places and dragging files to Notepad++ works jut fine. But dragging pdf files from the same locations onto PDF x-change editor doesn´t. The icon just kinda bounces back when I drop it.
If i run PDF x-change with a Bottles terminal, I see the following, although it doesn´t seem relevant. The last two error messages seem to appear randomly, not when I drop files on the app.
