Giving a spin to Mathematica for OS/2 - Symmetrical Multiprocessing (SMP) for v2.11 with 16 CPU/Cores in VirtualBox 7.0.6 built from source in Metztli Reiser4 / Debian Bullseye backports AMD64. TigerVNC froze multiple times after connecting to the remote headless VirtualBox instance. Accordingly, I had to use Remmina again for a decent VNC connection. Nevertheless, OS/2 v2.11 VM falls back to use the PS2 mouse hardware which causes the mouse position to drift from the real mouse pointer as it is moved in both VNC clients.

(Once the video player has started, right selecting (or 'clicking') your device (or 'mouse') will show menu option, 'Open video in new tab', which will enable larger screen size. Alternatively, the video with larger screen size may be shown in the Calli, i.e., 'Home', collection front page)
