Description of problem:
There is an option to disable effects (wallpaper/font-smooth/animation) and reduce color bit depth with using spice client options for Windows guest. But those options are not triggered automatically when WAN is detected (on server side) which was original purpose of those features (I believe). Please add this feature so that WAN support would be even improved.
Version-Release number of selected component (if applicable):
spice-client-0.8.0-2
spice-server-0.8.0-1
Windows guests
Spice window agent
How reproducible:
Always
Steps to Reproduce:
1. Connect using spice client to Windows guest in WAN environment (<10Mbps).
Actual results:
No effects are disabled. Color bit depth - 32bit
Expected results:
Guest has disabled effects
Additional info:
Partially RFE

I would love to see it triggered automatically when WAN is detected, when I execute it manually It does work, please can you then move it to the right component?

What do you mean by "execute it manually"? Do you mean running spice from command line with "-disable-effects all"?
And by WAN detection, do you mean the one time WAN detection we perform when the client is being connected?

Yes, when I run spicec with "--disable-effects all" option and connect to Windows guest, I can see that those effects are disabled, the same with --color-depth.

Yes, this RFE I meant about this, when client is being connected to Windows guest and low bandwidth is detected JPEG nad ZLIB over GLZ compression is enabled, and I would love to see that functionality as provided with --disable-effects would be automatically enabled too so that usability of Spice over WAN would be better. It's RFE. I do not know how much work it would requires (I guess It needs cooperation of multiple components), but I believe there are some benefits when we already have functionality of disabling those effects.

O.k. Created a bug for front-end as well #707582
I think these options (disabling wallpaper/font-smooth/ui-effects/all and changing the color-depth to 16 bit) should also be added to the user/admin portal, virt-viewer, and the controller, explicitly, or by a user profile (e.g. LAN/WAN/etc.) that implies which optimization should be done in Spice (and not necessarily just guest optimizations).
Moving to 6.4 due to the missing definitions from rhevm PM.
