Playbin does not show visualisations in some cases

[Yogesh Marwaha]

Hi,

In my program, I enable/disable visualisations in the playbin (whenever video 
widget is shown/hidden) by setting/unsetting respective flag of the playbin. 
The problem is that once the flag has been set and unset, setting it again 
does not cause the visualisation to appear until a seek is performed or uri is 
changed. This happens irrespective of the visualisation element chosen.

When this is done about 5-6 times in a row, playback pauses (a seek resumes 
playback). This is tested on pulsesink and alsasink.

Is my method of disabling visualisations using flag wrong or there is 
something unusal in the playbin?

Regards,
