Describe the bug

Some dialogs such as the Donate and long-press menus appear with light theme instead of dark, and having some white instead of black text on it making it invisible. It also affects the icons of the bottom-right control buttons where it shows black instead of white.
Enabling "Use experimental new API" did not make a difference.
Can be temporarily remedied until exit by selecting the Dark or Black theme again in Appearance Settings.
This did not occur prior to 5.2.0

Device

LG V20, 8.0 (Oreo)
