This PR made things look thicker, but also more blurry, just like the effect of disabling ClearType on Windows.
(left = this PR artifact, right = 4.4.0 release, same below)

Much more blurriness, if system level scaling is set to 125%:

And text edges become little jagged - distinct in certain (MuseScore) zoom values, likely 200%, 400% or 800%. Here's 400% for example:

As for #15242, here's a 3-way comparison.
MuseScore preview zooming 100%: (mid: this PR build, right: current master)

To me, comparing to v3.6, it looks like this build is using about the same rendering methodology, but without antialiasing. Notice how bad the "g" in "Change Instr." looks.

MuseScore preview zooming 150%, obvious jagged text:

I didn't include system level scaling because in 3.6 Palette and Score panel don't respond to it. Their contents stay at the same pixel size, no matter how big the surrounding elements are:

Which means there won't be any blurriness, but also no HiDPI support.

@igorkorsukov Tested on Win10 (2K display) and Win11 (FullHD display).
#23430 looks fixed, #24287 I can't check (unable to reproduce the bug)

About regressions, I have the same the results as @ShibuyaCyana

Comparing with master (and 4.3.2), text inside score and inside palettes became more sharpened on 100,200% and also more blurry on 125,150%

Also, I found that on Win11(FullHD) on 100% text of tabs in Preferences is shorter (with ...) when there is enough space. It's regression comparing with master (and 4.3.2)
