i can observe no fractional scaling on a default installation dell xps5790 even with a single monitor (4k).
Connecting a second monitor the scaling is not working separately either.
The most obvious effect is that the right side (top bar) goes off screen.
I tried scaling with different display resolution to no avail.
I eventually started just using a lower display resolution and gave up on fractional scaling.
