Bug introduced in V10.4 or earlier and persists through V12.0
A support case with the identification [CASE:3726810] was created.
[...] It does appear as though
UpdateInterval
is not working well withMousePosition
. As such I have gone and filed a report with our developers so that they may further investigate the issue. [...]
Dynamic[MousePosition["GraphicsScaled"], UpdateInterval -> 1,
TrackedSymbols :> {}]
Dynamic[CurrentValue[WindowSize], UpdateInterval -> 1,
TrackedSymbols :> {}]
Graphics @ Disk[]
Whether you move over a disk or resize the window, Dynamic
is updated at a high frequency, way more often than once per second.
Should this be considered the expected behavior?
Is there any work around?
UpdateInterval -> Infinity
or the typical encapsulation insideRefresh
doesn't seem to prevent the updating from being continuously. $\endgroup$
