Share Posted September 4, 2017 Hi, As the title says, just before starting the tween the background colour flashes to white. Only on Firefox. I've tried to '.set' and also '.fromTo' to 'force' the starting colour of the background but no avail. Browser: Firefox 55.0.3 (64-bit) Os: OsX 10.11.6 Device: MacBook Pro (Retina, 13-inch, Early 2015) Thank you See the Pen JyzqMy by quasiDigi (@quasiDigi) on CodePen Link to post Share on other sites
Share Posted September 4, 2017 Hi @quasi Use backgroundColor instead. And rgba has 4 values, not 3. 4 Link to post Share on other sites
