Can also reproduce on KMail 6.1.0. Aurora-DX 40 (based on Fedora Kinoite 40) KMail version 6.1.0 (24.05.0) KDE Plasma version 6.0.5 KDE frameworks version 6.3.0 Qt version 6.7.1 Linux kernel version 6.9.4-200.fc40.x86_64 KMail installed through rpm-ostree (from Fedora repos) |
Created attachment 170358 [details] Screenshot of Kmail message viewer SUMMARY I've set my screen to 165% fractional scaling for this test; it looks similar with 150% or any other reasonable fractional scaling. While the rest of KMail or Kontact looks pixel by pixel as it should be, the mail view window looks badly scaled, not even blurred, but pixels getting twice as large. STEPS TO REPRODUCE 1. Use Wayland and set main screen to fractional scale 150% 2. Open KMail or Kontact to look at a test mail (HTML or plaintext) OBSERVED RESULT Badly scaled text, where individual strokes have different size (look e.g. at an “m”). EXPECTED RESULT Well rendered text, see the menu for comparison SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Kontact 6.0.2 (24.02.2) (available in About System) KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1 ADDITIONAL INFORMATION I'm looking through KDE which parts are not working well on a fractional scaled output, and this is one of the few cases I found. For the components, it is a subcomponent of the message list, which otherwise is fine.
