--- Comment #9 from Dobroslaw Kijowski <dob...@gmail.com> ---
I've noticed similar issue on Arch Linux with latest Plasma (5.27.3). I'm using
two monitor setup with 125% scaling. Out of curiosity I've backported two Qt6
patches regarding fractional scaling. The repository with backports is
available at:
https://github.com/dobo90/qtwayland/tree/kde/5.15_fractional_scaling. After two
days of testing I've noticed following things:
The bad ones:
* Sometimes fonts are "pixelated" (for example when opening Monitor Settings).
* Some of the icons are also "pixelated" (for example icon of QTerminal in
About dialog).
* LibreOffice renders way too big text (it's not usable on Qt backend).
The good ones:
* The are no artifacts (horizontal blinking lines) in QTerminal application
(previously they were really annoying).
* Fonts seem to be more readable (maybe it's only my subjective opinion).
I've tested also the qt6-dpi.py application mentioned here. It reports
devicePixelRatioF equal to 1.25 (instead of 2.0). I can clearly see the
difference in font rendering (when comparing two screenshots - before and after
enabling fractional scaling). But I don't know how should I interpret the
rendered test image.
This is my first comment in this bugzilla. I haven't done any Qt/KDE related
work yet - I've just noticed a slight font blurriness on Plasma. If my comment
is irrelevant, please ignore it. If someone wants to test my changes I would be
very glad. Maybe in the future it will be possible to add
wp-fractional-scale-v1 to Qt5 guarded by an environment flag (for example). I'm
aware that Plasma 5 is in a maintenance state but well..
