In 8.2 beta, if i save a live.meter~ with a transparent background, it will be back to the default bgcolor when the patch is saved, closed and reopened. This is not the case with Max 8.1.

If a live.meter~ in a patch saved by Max 8.1 has a transparent bgcolor, Max 8.2 opens that as expected.

I believe Max 8.2 is saving the bgcolor, but is also saving a blank expression as bgcolor under "saved_attribute_attributes" and therefore is not recalling it correctly on patch load. here are some lines from inside the Max 8.2 patcher file:

"bgcolor" : [ 0.156862745098039, 0.156862745098039, 0.156862745098039, 0.27 ],
…
"saved_attribute_attributes" :                     {
                        "bgcolor" :                         {
                            "expression" : ""
                        }

in a patch saved by Max 8.1, this "saved_attribute_attributes" is not present.

Example patches saved by both versions attached.

* I have not tested enough to know how widely this bug applies – to other objects or to setting any bgcolor even if not including alpha.
