How to disable xinput2 on Linux with X11 and Qt 6.7.3
-
There is a old bug in X11 that applications with xinput2 enabled will always ignore the first scroll tick after their windows re-gaining focus. There is a environment variable called GDK_CORE_DEVICE_EVENTS in GTK which enforce applications fallback to GTK2 style input. With it, the first scroll will not be ignored.
I wonder if there is a similar option in Qt?
