Hey!
Since last Windows Insider-Preview Buidl 17025.rs_prerelease.171020-1626 i have no toggle boxes inside the installer. Problem only occured inside Aslain installer and I can not verify this behaviour in other applications. Problem occurs not only on this special page, all other installer-pages are broken too.
If you need further information feel free to ask
