Kmail font rendering 125% scale, wayland, blown 300% no filter
Id like to add to this. I run my desktop at 125%, in wayland, and attached a screenshot, scaled 300% in gimp. The font rendering issue only seems to affect the kmail message pane, other text in plasma6 is fine. *** This bug has been marked as a duplicate of bug 482128 *** I can confirm this behavior on wayland, plasma 6, kmail 24.02.1. Only in the message pane, where the email content is displayed, fonts are not renderered sharply. This increases when we switch to HTML mode. I can confirm as well. But I think it was correctly marked as a duplicate of Bug 482128, which is caused by this Qt bug https://bugreports.qt.io/browse/QTBUG-113574 Operating System: Arch Linux KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 Kernel Version: 6.8.7-arch1-2 (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 7900X3D 12-Core Processor Memory: 93.5 GiB of RAM Graphics Processor: AMD Radeon RX 7900 XT Manufacturer: ASUS *** This bug has been marked as a duplicate of bug 482128 *** |
Created attachment 166415 [details] screenshot of a test email in kmail SUMMARY On Plasma 6, font rendering is broken when reading emails using kmail on a scaled (hidpi) display. Please see attached screenshot for a beautiful preview. All other components of kmail scale and render fine. STEPS TO REPRODUCE 1. Use wayland (not tested on X11) 2. Configure display scaling (only tested on 125% and 150%) 3. Open an email in kmail. Both HTML and text format are affected OBSERVED RESULT Blurred, unhinted fonts EXPECTED RESULT Clean, well rendered and hinted fonts.
