Touch scroll way too fast with KDE Plasma 6, 1280x800 7 inch screen, Wayland session, and DPI scale 175%

With the specific setup of KDE Plasma 6, 1280x800 7 inch touch screen, Wayland session, and a DPI scaler 175% set in KDE system settings (combined with the option that legacy X11 apps are scaled by the system and not by themselves), the vertical touch scroll in XFCE 4 Terminal is way too fast.

The scroll speed seems to be something extreme like 10x farther than the actual distance the finger travels on the screen, making it almost impossible to just scroll a few lines. Such a small movement will instead often be interpreted as a short press, long press, or text select, and cause some menu or the touch keyboard to come up unintended.

I'm reporting this with XFCE 4 Terminal specifically, because gedit (GTK+ app) and kate (Qt app) and Firefox (I think GTK+ app...?) are entirely unaffected b this and have a touch scroll speed that roughly matches the actual travel distance of the finger.

Affected XFCE 4 Terminal version: 1.1.3 (4.18)
