Problem with fractional scaling
I'm running GNOME with fractional scaling (150%) on a HiDPI display. The Calibre UI looks very good here, except the ebook-viewer. It opens ebooks initially too small (not fitting the the window size) which can be fixed my resizing the window slightly. But besides that, the fonts (both, of the e-book and the viewer-ui) look coarse and washed-out.
With a scaling of 100% or 200%, everything looks ok. Is there anything I can do about it? I wonder why it happens only in ebook-viewer. (Running the official binary install (calibre 7.3) on Fedora Linux 39) Last edited by beedaddy; 01-19-2024 at 02:49 AM. |

because only the viewer uses qt webengine and no nothing you can do about it.

I use KDE rather than GNOME, but I had a similar problem. Setting the environment varaible
Code:
