Phase One Capture One 12 crashes Windows 10 guest -> fixed after 6.0.4

[alexsh]

After upgrading virtualbox from 5.2.22 to 6.0.2 I noticed that the display performance got really sluggish with frequent hick-ups. So I changed VBoxVGA to VBoxSVGA, which helped somewhat.

But now, if I run Phase One Capture One 12, the guest (Windows 10) freezes and restarts after a few seconds.

Disabling OpenCL in Capture One preferences helps somewhat (no restart on application startup), but sometimes the restart still happens when doing image manipulation.

You can download Capture One 12 trial here: ​https://www.phaseone.com/en/Capture-One.aspx

Graphics Controller: VBoxSVGA
Guest: Windows 10 1810
Guest OS additions 6.0.2 installed.
Host: OpenSUSE 15.0
Host GPU: GeForce 1050, nvidia 390.87

Thanks!

Forgot to mention, I have CR_RENDER_FORCE_PRESENT_MAIN_THREAD=0 set in my host. Both 3D and 2D Acceleration are enabled in VM Settings.

You forgot to attach VBox.log of a VM run where a freeze or restart occurred.

I've tried the application and it seems to work fine. You have to provide step by step instructions which will reproduce the problem. It is impossible to guess what "when doing image manipulation" actually means.
