I just got this today and n matter what I do it shows me a white screen if anyone could help me with this issue it would be greatly appreciated.
This issue is still sort of a mystery, it's been happening to a lot of people but not to me. Some times it fixed by just restarting your computer some times it's your antivirus messing around without telling anyone about it. (looking at you AVG) Some times it is an error that i can fix.
Can you rightclick the settings cog on the top right of the app? It should bring up a debug window, there might be some errors in the console tab. (among with a lot of other messages)
If there are can you please copy/paste them into this thread.
