For OP could you please clear icon cache [1] (or reset user profile) and retest.

We saw similar at 6.2.0 as in bug 119020

regression?


=-ref-=
[1] the scaled PNG bitmaps each icon theme is cached in a folder in %appdata%\LibreOffice\4\cache\  simply delete. It will be rebuilt next launch.

I did so, deleted all in %appdata%\Roaming\LibreOffice\4\cache
when i restarted calc, it loaded a bit (obviously)
but i do not think that you meant that this will fix it, icons look still different (widened/pixelated) on 4k screen with 28inch.

You can see the difference, i have a 2nd screen with 1080p, 23inch, see below the differences..

i think i hope i have brought more light into the issue

Please try any SVG icon style available under Options->LibreOffice->View.

Your initial screen clip-- https://i.imgur.com/iFFfthW.jpg -- shows corrupted RGB channelization on scaling. That was bug 119020 -- happy if that has not returned!

Otherwise for HiDPI monitors as Mike K notes, try one of the SVG icon themes,e.g. 'Colibre (SVG)', from Tools -> Options -> View 'Icon style:' drop list.

The SVG icon themes are how we support HiDPI requirements.

Still an issue? Tried an SVG icon theme?

You could also test with the Skia backend in a dev build: https://dev-builds.libreoffice.org/daily/master/current.html Take one from Win-x86_64@tb77-TDF
Tools - Options - LibreOffice - View - Use Skia for all rendering

Set to NEEDINFO.
Change back to UNCONFIRMED, if the problem persists. Change to RESOLVED WORKSFORME, if the problem went away.
