I have a “1px bug” when I try to animate this block of 10 images.
On load : no problem
On hover on : the blue or orange masks don’t match anymore with the background image and the parent (around 1px)
On hover out : the blue and orange masks don’t return properly (1px around)
On Retina displays (with Safari, I have tested with my MacBook Pro and Ipad) this effect is minimal.
But with my MacPro and on Eizo 27 monitor, this effect is real and I can’t sell that to a client.
I always work in Webdesign with several devices (smartphones, tablets, laptops and so on, Mac and PC systems, all main browsers in game).
I can reproduce the problem (1px linked with overflow: hidden parameter) with all devices I have and all browsers, 4k, HDPI and normal screens, Mac and PC. Ok! It’s not a catastrophe. But I found this not good enough for my quality management.
