Struggling with TeXmacs on 4k screen under Linux

Looking at the Qt version history and Qt’s page on high DPI, it seems that possibly relevant functionality has been introduced in versions 5.6, 5.11 and 5.14.
Version 5.12 is the latest LTS, but will only be supported until December 2021. It seems that after v6 will be the only open source release receiving bug fixes.

I’m curious to hear more about your experiences with Qt. I’ve been looking into a potential move to v6, but my experience with Qt is fairly limited. What are the reasons for sticking to 5.6 or 5.8?

The KDE team will do bug fixes for Qt 5.14 in the form of patches to the last release for a while. That was part of the agreement between KDE and the Qt Company https://dot.kde.org/2021/04/06/announcing-kdes-qt-5-patch-collection

This is a very annoying problem.

Are there any GNU Linux systems for which the fonts are displayed correctly with QT_SCREEN_SCALE_FACTORS different from 1?

If not, then we might simply set QT_SCREEN_SCALE_FACTORS to 1 under GNU Linux.

I can confirm that the official build with Qt 4 does not have this strange issue, so it’s probably related to how Qt 5 handles stuff.

Thanks fan. Yes, that version seems to work flawlessly on my system as well.
