Is it possible to shrink an APFS Mojave vdisk ?

Is it possible to shrink an APFS Mojave vdisk ?

That was probably the case. The "Black Screen Patch Vega 56/64, RX580 etc. (c)Pike R. Alpha" patch from the drop-down list in Kernel and Kext Patches solved my DP issue.

I currently use HDMI because with DP the monitor loses signal during the initial loading screen with the Apple logo and the progress bar.

Thanks, it worked. However the display randomly glitches and turns black/shows static for a few seconds, any ideas ?

Hi, I'm trying to setup a macOS Mojave VM with GPU passthrough. I followed all the steps from the video but I can't get the VM to recognize my RX 480, the monitor doesn't turn on and About this Mac doesn't show any GPU at all. I can however remotely access the VM. Here are the VM XML and the config.plist XML.
