Bug ID: 488324
Summary: Fractional scaling of mail view window looks badly
scaled
Classification: Applications
Product: kmail2
Version: 6.0.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: message list

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.
