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???

Confirmed on gwenview from git master.
