We have a couple of users with an issue opening PowerBI.
This issue has been narrowed down to 4k laptops with multiple 1440p monitors connected.
They can open PowerBI correctly on the laptop screen at 4k / any DPI scale...and move the application to extended monitors without a problem. The issue is when the laptop is docked and only using two connected screens. No matter the configuration PowerBI will open as below.
Windows 10, November Update PowerBI. Cleared temp files and appdata folders related to PowerBI.
Tried 'Disable display scaling on high DPI settings' under executable options. Also tried compat modes.
