None of the x11 sessions in any DE were as smooth video output-wise as the Wayland sessions I tried, especially with multiple monitors, they always had various problems and stutter.

That is why I switched to Wayland in the end.

1. They have an experimental Wayland session already. It mostly works except for some pretty important stuff…I also haven’t seen development on it for a long while.
2. I think this is almost a 100% no.
3. I tried to implement that myself. Making them shorter than the screen is easy. Making them appear above the edge of the screen is hard, but not impossible - the code is in JavaScript and the logic is kind of disjoint across multiple files and stuff depends on panels being at the edge of the screen - I didn’t do it in the end because it was too much effort for something I didn’t want that much.

I just insert the Tragedy of systemd video as my usual response to these threads.

Not really the easy way, but this is how you can make your wine application show up in Preferred Applications.

You probably don’t have a .desktop file for you wine app. Go to /usr/share/application and find one entry that also shows up in your Preferred Applications->PDF list. Open that entry with a text editor: that’s how your new entry should look like (I recommend looking at /usr/share/applications/xreader.desktop in particular). You must have the MimeType field for Preferred Applications

Create your new pdfxchange.desktop file and place it into ~/.local/share/applications so it will be picked up by the OS and it should show up in your Preferred Applications list.

The only thing you need to figure out yourself how to make pdfxchange open a file from the command line, you need to put that into the Exec= field.

For you it might be something like this: Exec=env WINEPREFIX="YOUR_PDFEXCHANGE_WINE_PREFIX" wine "YOUR_PDFEXCHANGE_WINE_PREFIX/drive_c/path/to/pdfxchange.exe" Z:%f

Try it in the terminal (without Exec=) until it works. %f is the file you want to open.

I have the same issue on my laptop, except it’s constant from the moment I log into Cinnamon. Other DEs are fine.

In the end I was too lazy to troubleshoot it, but maybe I’ll try with the Wayland session. If that has the same issue, something’s gone terribly wrong.
