Compare 'kde5' and 'gtk3': <https://i.imgur.com/zIC0pVg.png>,

The bug is first reproducible on 6.2.0.1 and the screenshots were made on
6.2.1.2 -- the latest stable release available at the report time.

6.2 Release notes introduce kde5 switch:
<https://wiki.documentfoundation.org/ReleaseNotes/6.2#KDE_5_.2B_Qt5>, so the
bug is present since the beginning of this switch.

Toggling 'Use OpenGL for all rendering', 'Use antialiasing', 'Use hardware
acceleration', 'Screen font aliasing' does not resolve the issue.
Toggling '

Steps to Reproduce:
1. Download any RPM from official LibreOffice website of version 6.2.0.1 or
higher.
2. Extract into LibreOffice_6.2.0.1_Linux_x86-64_rpm.
3. $ cd LibreOffice_6.2.0.1_Linux_x86-64_rpm && ./install RPMS out
4. $ SAL_USE_VCLPLUGIN=kde5 ./out/opt/libreoffice6.2/program/soffice

Actual Results:
All rendered contents except the menu strip are blurry (not antialiased).
