Hello. After upgrading to 5.2.20 remote VNC connection succeeds but only shows black windows of default size regardless of what happens on VM. VM works perfectly, there's just no image on VNC. Tapping keys over VNC window makes them go to vm correctly. Thanks in advance.
I have the same problem, noVNC and or tightVNC shows only black screens.
Same problem here!
Same problem occurs on my FreeBSD box (11.2-RELEASE-p4 / amd64) Client: UltraVNC (on Windows10) and Chicken of the VNC (MacOS)
I confirm, FreeBSD 11.1 and 11.2.
If you have set 3D Acceleration, try to disable it.
Was disabled. 2D enabled.
2D/3D enabled/Disable does not help at all to get output visible at all. For me it's clear that 5.2.20 changed something to break this. 5.2.18 is fine. 11.2-RELEASE-p4 / amd64 for me too
Same problem here. Host 12.0-BETA1 r339549, port virtualbox-ose-5.2.20. At least I know I am not the only one experiencing this issue.
FYI, there's a ticket open in the virtualbox site as well: https://www.virtualbox.org/ticket/18072
I confirm, FreeBSD 12 beta 2 (amd64)
Just tested with vbox 5.2.22 again on 11.2 p4 x64. Same problem occurs, only black vnc screens.
Same here: 5.2.18 work fine, 5.2.20, 5.2.22 - black screen 640x480, but keyboard work.
Created attachment 199654 [details] patch after patch https://www.virtualbox.org/attachment/ticket/18153/vnc_fix.patch novnc output working again on 5.2.20 and 5.2.22 versions.

(In reply to Dutchman01 from comment #13) Works for me on 5.2.20. Thanks!
