Crop "jumps" in Flash when using scale="0.6". Flash bug?

Hi guys!

Today almost crashed my mind with the following issue and finally found out the reason. Take a look:

Upper buttons have scale=0.6 and lower ones have scale 0.5. In html5 all is fine, but in Flash upper buttons "jump" one pixel up and down when switching crop, this is very clearly seen in the left button. I've spent brain-storming hours adjusting buttons inside the .psd file and then checking crop values, but finally found the reason. Seems like Flash has some troubles when scale is set to 0.6.

the code is here:…g_test/tour.xml

Any thoughts?

no, that's not a bug - when scaling images irregularly, there can be always some scaling and interpolating issues like this.

The internal details in Flash are a little different to HTML5 and at same stages it is not possible to use fractional pixel positions.

Best regards,
