Having installed rEFInd 0.12 in order to dual boot a Windows 10 and Manjaro installation, I stumbled upon a rather annoying problem: Windows 10 does not complete its booting process when I have both my dedicated and integrated GPU active at the same time. Turning off the iGPU in the BIOS ensures a successful boot.

Windows' boot process gets quite far, it only stalls (black screen, mouse/keyboard turn off) after the "circling dots" animation. Weirdly, rEFInd seems to be the cause of this: using the Windows boot manager directly or booting via Grub using the same setup shows no issues.

Unfortunately, turning off the iGPU is not an option for me, since my second display can only be driven by the iGPU (without buying adapters etc.). The Manjaro boot is not influenced by this problem.

I'd like to know how I can provide debugging info such that this problem can be understood. As a starter, these are the relevant hardware components:
CPU: Intel i5-4460
 GPU: AMD Radeon RX 590
* Motherboard: Gigabyte G1 Sniper B6 (running BIOS rev. F3)

Cheers!
