hi @Stefano_Fresch it seems that issue only happens in Safari. The way I have been able to solve it is to increase init image size to 1.01. Only I have done was to set initial image state(size) and set this value on mouse out
you are a genius. Thank you very much for your solution. It works. I have a very diffucult client and for me it is so important to debug these kind of stuff ! Thank you again
