Poor fonts in preview using WebEngine renderer under Linux Wayland with fractional scaling

[callegar]

In the arrangement in subject, the quality of the preview is very poor, with many scaling artifacts, as if the preview was first rendered to a bitmap and then scaled up by my fractional scaling ratio (150%).

Hi!

I cannot reproduce this issue: I tried on GNOME (Wayland), with ReText from master branch, Qt 6.7.2 and QT_SCALE_FACTOR=1.5. Here is a screenshot (unscaled ReText also included for comparison):

Can you please provide your screenshot, and details about your desktop environment, ReText and Qt versions?
