I had similar experiences but some layers are Citrix and others RDC. Seeing your situation brought back my anxiety on those connections. Sorry for this. Is there any terminal servers to be able to ssh port forwarding? Thus to reduce layers, while as the test setup is gui based at least one layer of RDC is required. Reducing nested Remote Desktop would for sure help with the experience. Sorry again for you situation.
