#1 Updated by Leonid Protasov about 7 years ago

The same goes on with Youtube plugin. Looks like any plugin that changes background on the run suffers that.

  • Target version deleted (4.4)

I don't think the leak is that big actually. It has always been like this and will only leak when unloading the plugin (uninstall or exit). I don't dare fix it for 4.4 as it might break other stuff. I've tried to fixed it before but it was a bit too nasty.
