> I have an issue when connecting to VMs where the resolution is set differently to the normal 1024x768 resolution. The JS client doesn't receive a second `size` (command?) from the java client, as it used to in our old 0.9.14 installation.
> Steps to reproduce:
> # Create a Windows 10 VM in Hyper V (or graphical Linux, I don't think guest OS matters)
> # Connect to the VM from guacamole, without enhanced mode
> # Set the VM resolution to 1152x864 (the display is resized accordingly)
> # Disconnect the cuacamole session
> # Reconnect the guacamole session
> # VM display fails to appear
> Versions:
> * Guacamole, everything 1.3
> * Hyper-V Server 2019, Windows 10, no version change for hyper-v between upgrade from 0.9.14 and 1.3
> * FreeRDP version 2.2 (buster backports)
> Guacd debug:
> Guacd is receiving the updated resolution from FreeRDP, and I checked FreeRDP using xfreerdp which works as expected. Debug logs, that I think are relevant, are:
