Video settings of some channels overwritten

Hi,

I have a weird bug with some channels. Sometime, I switch from a first channel and the stream of the new channel freeze. So I switch to an other channel and when I switch back to the channel, it has the video settings of the first channel :

(example) channel 2 (working) -> channel 3 (freeze) -> channel 4 (working) -> channel 3 again (working but with the video settings of channel 2)

It happens each time a channel freeze and the previous channel have different video settings.

Is it a known bug ?

Regards.
