Thank you again, We tested the AutoAlpha instead of Opacity and there is major performance enhancing but the issue still exist, I will try to make an isolated sample of code to reproduce the issue.

Thank you for your reply. I agree with you that the sprite sheet is a lot easier but unfortunately, We can't re-do all the website animation now with the sprite sheets and We have tried before the sprite sheets but we faced problem that the sprite sheet dimensions is too big to load because every image in the sheet was around 1000 x 600 px and we had more than 100 image. You can take a look on the website from this URL http://thecorvus.com/teto283/ Regards,

Hi guys, Thank you for the great library and you continuous support. I have an issue, I’m developing a website based on a story and I used GreenSock library specially TimelineMax to build this website, the problem now is, Im using frame by frame animation and Im toggling between 0 and 1 values of Opacity to achieve this animation, for example: var is_force3D = false; var forest_moving_sq_background_moving = new TimelineMax(); var forest_moving_corvus_walk = new TimelineMax({repeat:18}); forest_moving_corvus_walk.to('.walk2', 0, {opacity: 1, delay:.09, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk1', 0, {opacity: 0, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk3', 0, {opacity: 1, delay:.09, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk2', 0, {opacity: 0, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk4', 0, {opacity: 1, delay:.09, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk3', 0, {opacity: 0, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk5', 0, {opacity: 1, delay:.09, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk4', 0, {opacity: 0, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk6', 0, {opacity: 1, delay:.09, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk5', 0, {opacity: 0, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk7', 0, {opacity: 1, delay:.09, force3D:is_force3D}); forest_moving_corvus_walk.to('.walk6', 0, {opacity: 0, force3D:is_force3D}); forest_moving_sq_background_moving.add(forest_moving_corvus_walk, "-=21.875", "sequence"); And It works as expected on all browsers except Safari, Sometimes all frames take Opacity 1 at the same time and this makes all the frames appears together and this not happening all the time. You can see this video for the working case: And this video for the bug: I appreciate your support, Regards,
