Just detected that a code part prevent updates to be faster then 7FPS.
Can't trace back how long this error is already in the source, but at least a few versions.

will be fixed in 1.1.9.1

Seriously!?
Does that mean the server only ever delivered at 7fps, or the viewer only ever polled at that rate?

It's an internal server timer.
Normal, it should only limit the updates while the mouse moves.
This give priority to the mouse.

But, the server engine market the mouse as moved for all updates...

Would that explain the 'flickering' one sees in the mouse pointer when everything is static?
This is a very good find!

No,
Cause is the polling.
The bitblt() function grab the screen data to check if some pixels changed ( polling).
Site effect is that the cursor flicker.
