B-2b is the vGPU type? meaning T4-2B ?
Does it help if you configure it with T4-2Q (may require a different
license)?

Only a single Display, right ?

Are you running spice-streaming-agent on the guest ?
Try to stream with H264, if you do not already do it
(may require paying fees for using H264).

Is 4k resolution a requirement? If not, try with e.g. 2k.

Hope that helps,
    Uri
