[Gui] New transparency property not applied

[kisolre]

Edit: looks like the problem is from some of the addons that i have. No time to investigate now. Somebody might try the differences between mine, their and DrMacros combinations.

There is a new "transparency" setting under "PD/shape appearance" which I waited a lot to appear. But setting it has no actual effect on the newly created bodies. They still have Transparency=0. Could anyone confirm?

Seems to work on newly created Pad objects.

Could it be one of your many Addons causing the issue?

Sadly looks like it. I tried vanila config and it works. No time to investigate now

[Syres]

I tried vanila config and it works.

OK, that was a big change, using my Linux partition I initially could replicate the fault and removed each of my Addons one-by-one to no avail. Then I got a new user config alongside my existing one and to cut a long story short concluded that if the default shape colour is Hex #cccccc (light grey) then the default transparency works as expected but and it's a big but, long-term users such as ourselves have a default shape colour of Hex #9b9b9b (dark grey) which the default transparency doesn't seem to work along with Random Colour selected so probably best to say it only works with #cccccc.

I'm guessing you are not aware of this

Edit: Clarified only one colour appears to work correctly.

[Syres]

I might have a fix, certainly seems to work for me https://github.com/FreeCAD/FreeCAD/comp ... D:patch-47

[kisolre]

Yes, I also have "Random color" active.

[uwestoehr]

They still have Transparency=0. Could anyone confirm?

Confirmed, but only when one uses random colors.

I had now a look but cannot find where the random color would make the difference that the transparency is not applied.

The code is in

OK, I found the issue and fixed it:

However, it is still not clear to me why the random color triggered it.

Thanks, all looks good
