Windows 10 crashes on Ubuntu 18.04 Host

[roemer2201]

Dear All,

I'm running a Windows 10 x64 machine inside virtualbox on a Ubuntu 18.04 x64 Desktop. The VM crashes or rather freezes randomly. What I can see from a users perspective is that the VMs window on the host desktop crops down to 640x480 px with no apparent reason and the VM seems to not be able to handle it and freezes. The Windows 10 inside is not able to log anything. The VMs process itself does not crash, I can reset the VM (Host-Key + R) and it boots up again. This is what virtualbox logs on these events, full log is attached:

Currently I started the VM in headless mode from the CLI and RDP'ed into it, no crashes after multiple days of usage.

Thank you for your help in advance!

00:00:06.772445 File system of '/media/raid/VMs/Virtualbox/vmrbreb10/vmrbreb10.vdi' is btrfs

You are using the system drive from a NAS?

No, the /media/raid mountpoint is a local BTRFS (Raid 1) filesystem consisting of 6x 2TB.

Disabling 2D acceleration helps and the VM did not crash anymore so far. Although I find the VM being a bit more unresponsive like when writing a text sometimes letters have a delay/lag of half a second or so.
