https://github.com/tildearrow/kwin-lowlatency/blob/Plasma/5.17/wayStart#L97

https://wiki.qt.io/New_Features_in_Qt_5.14 Added the QT_ENABLE_HIGHDPI_SCALING environment variable which enables high-dpi scaling based on display DPI. Replaces QT_AUTO_SCREEN_SCALE_FACTOR (now deprecated), and corresponds to the Qt::AA_EnableHighDpiScaling application attribute.

System information:

Gentoo multilib systemd
GCC 9.2.0
cmake 3.14.7
Qt 5.14.0_beta2
Plasma 5.17.1

Possibly related, vlc is now unable to start:

What?! The variable I relied upon for proper HiDPI support will be deprecated?

The wayStart script has not been updated because Plasma 5.17 replaces the startkde script with a binary startplasma-x11.

Not fixing as I removed the wayStart script (because they turned startplasma into a binary, and that would mean pulling in another repository for it).
