Opacity set permanently when using flash

[AymanLyesri]

Hey, thanks for creating this plugin, just a little problem with the flash effect.
When set, it changes the active/inactive_opacity of the affected windows permanently until they are closed and effect is disabled.

before applying effect

after applying effect

btw i tried setting different flash_opacity values in the plugin section, all with the same results

full settings used
