Mouse scaling issues

#17

#18

The build from #18 and stable has an issue where the mouse is double the normal size. Might be another Qt problem..

Two notes:

• Can you test last update to Sioyek flathub?
• Can you provide a link to the PDF in your screenshots? so I can compare better in my system..
