Hi Ryan,
Now that you point out what the cause of the issue is, it makes sense. I
had to add cursor blending support for a customer requirement to correctly
handle multiple users connected at the same time on the same session. RDP
has no message to notify multiple connected clients of cursor movem
The regions under the mouse cursor are being updated at full blast. I
believe the issue is in x11_shadow_blend_cursor, disabling it drastically
reduces bandwidth usage. I'm suspecting the cursor is being added to the
image and then compared against the next frame which does not have the
cursor trig
Hi Ryan,
In certain cases xdamage can return useful information, but to be 100%
certain we would still need to use it as a hint and perform comparison on
the next and previous frame to detect regions that have truly changed. If
you want to use it, I've got nothing against it, it's just a matter of
Thank you Marc, useful information.
I did some exploring with XDamage today and the information returned seems

I noticed on master that my WAN upstream (all 1Mbit of it) is bei
Hi Ryan,

being invalidated on every pixel change. This happens with compositing

There are two commits that removed the functionality:
