ADDITIONAL INFORMATION

Comment 1 prasol258@gmail.com 2024-08-30 09:50:09 UTC 
can confirm, issue only happens on Wayland
Setting WAYLAND_DISPLAY="" and launching gwenview results in correct birds eye view.
Comment 2 prasol258@gmail.com 2024-09-01 08:46:51 UTC 
Seems like the birds eye view is just unaffected by fractional DPI scale on Wayland, which causes it to render using the wrong bounding box size???
Comment 3 Justin Zobel 2024-09-02 05:15:27 UTC 
Confirmed on gwenview from git master.

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Gwenview 25.08.0 (the latest released version)?

Yeah, I think this was fixed a while back. I've just checked again and it is fine.
