Why does the cursor move so slow in the menus?

Feels like a snail trying to sludge thru molasses in 2 feet of snow uphill both ways.

I also have this problem. I could partly fix it when deactivating Vertical Synchronisation. Then the mouse pointer moves as expected in the main menu or whenever driving is paused. But in menus like the new F6 since 1.58 I still see an acceleration and deceleration when starting and stopping mouse movements, like a hysteresis. In both games, ETS2 and ATS.

There is a setting, Graphics -> Image Quality -> Scaling, that I changed to 400% the other day. There is also a hint about "large impact on performance" in its description. For me the mouse pointer speed in the F6 menu is good enough at 100% but the delay increases at the other settings 200%, 300%, and 400%.
