White transparent screen windows phone 10

Hello,
I upgraded to windows phone 10 (Windows mobile 10) and a white transparent screen is displayed which i believe occurs when a message dialog is shown.
Now this problem occurs at the following events:
-When i need to accept a certificate when i connect to a wireless network(I think.. Not sure)
-When i need to allow a app to: Location, Music Library etc.(I think.. Not Sure)
-When i open 6tag and i have music playing.(I'm 100% sure)
So all this leads to one conclusion:
That white transparent screen is a message dialog.
It is white because i have the theme set to White.
When i change the theme to dark, Then it is black transparent.

Phone details:
-Lumia 535
-Build: 10080
-Carrier: CV NL

Please help me..

BTW: Images that are attached: are in theme dark..
