I've noticed that the right panel extends over the end of my screen when switching to the linear or radial filter tool. Such problems have existed in the past for the German translation. This time, it's not obvious which string could be responsible for that, there are no long words that wouldn't fit in the minimum panel width.
Where can I report such bugs? There's no feedback or support option in the menu.
Zur schnellen Lösung kannst Du einfach das rechte Panel etwas breiter ziehen.

Seems the problem has been resolved. I can't see it anymore in Lightroom 6.2.
