--- Comment #3 from Kurt Hindenburg <khindenburg at kde.org> ---
Git commit 35c5bc11094e56aece691ef574fe93456beab96d by Kurt Hindenburg, on
behalf of Luis Javier Merino Morán.
Committed on 30/12/2022 at 16:49.
Pushed by hindenburg into branch 'release/22.12'.

Fractional scaling and Antialias don't mix well

This is bug #373232 again.  The rendering rewrite in 76f879cd7 reenabled
antialasing in a too wide context, causing the bug to reappear.

After #373232, the situation was that QPainter::TextAntialiasing instead
of QPainter::Antialiasing would be enabled depending on the "Smooth
fonts" setting, and QPainter::Antialiasing would be enabled depending on
that same setting just for TerminalPainter::drawLineCharString().  Go
back to that situation.
