The QT6 tooltip is in black font on XFCE

[Ypixcm]

Hi ,I found a strange thing, the "tooltip" of the qt6 program is always black under XFCE, but there is no problem with Openbox

I tried setting up kvantum to no avail ：

Don't use kvantum ：

Is there a way to force the color of the QT tooltip?
Thank you

Find out what Qt platform plugin you use; most probably, that color is forced by it. You can find it with:

echo $QT_QPA_PLATFORMTHEME

If you use qgtk3, it's known to cause such problems. Replace it with qt6ct or any better plugin.

BTW, if I were you, I wouldn't use /etc/environment for setting my session EVs; doing so could cause a headache later. Most DEs have their own ways of setting session EVs (although I don't know about XFCE).
