Bug ID: 466744
Summary: wayland: 2 monitor setup with 175% scaling on one
screen and 100% on the other causes various problems
Classification: Plasma
Product: plasmashell
Version: 5.27.2
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

Depends on: 466683
Blocks: 466736, 466738, 466739, 466740, 466741
Target Milestone: 1.0
+++ This bug was initially created as a clone of Bug #466683 +++
Operating System: Fedora Linux 37
KDE Plasma Version: 5.27.2
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.1.14-200.fc37.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 8 × Intel® Core™ i7-7820HQ CPU @ 2.90GHz
Memory: 31,1 GiB of RAM
Graphics Processor: Mesa Intel® HD Graphics 630
Setup:
Laptop with 2K Laptop screen and a fullhd screen (1920x1080) connected by
displayPort
Use fullHD monitor as 'primary' and perform all tests on the fullHD monitor
(ignore laptop screen)
Go to systemsettings > display config
and set 175% scale for 2K laptop screen, 100% for fullhd screen.
This makes apps/windows on both monitors the same visual size.
Problem:
The font renderings on the fullhd monitor are not as clear/smooth as compared
to normal (100/100% scale).
- This affects the font-rendering which appears pixelated
- The kerning/hinting of letters is also bad (font hinting is set to 'slight',
but it gets worse with medium or full)
This is especially noticeable with small fonts like in thunderbird, a browser
like chrome/firefox and typical webpage-fonts render smoothly. In my case, i am
using Tahoma (ttf) with 8px size.
As indicated above, switching to 100%/100% on both monitors solves the problem
