Scrolling in the middle part of this website is very slow: https://www.rocketbeans.tv/wochenplan/
This seems to be caused by the opacity on the "#schedule2017 .weekInner .day.blindfill" elements, which have fixed backgrounds.
The testcase shows the same slowness.

Nightly 61 x64 20180430100522 de_DE @ Debian Testing (KDE, Radeon RX480)
main profile. (a fresh WR profile looks the same)
Current look. Mostly a square only shows up if I click on it.

(In reply to Jan Andre Ikenmeyer [:darkspirit] from comment #2)
It's only broken if the height inside Nightly's KDE/gtk3 window is >= 1099px. The window width doesn't matter.

The WR side fix should be in the current WR update (i.e. the one on autoland). So presumably this will be fixed in the next nightly.

The WR issues have landed, do you still see this problem?
