Worked: 4.1.1

For me, zone overlay is not visible prior to b11d8d2e74
Also, it seems there are intentionally made non transparent: !110697

  1. but it have transparency/alpha in the theme
  2. in the simpliest case, when simulation zone framed, it covers title

What kind of issues appear with transparency? What is «tricky theming?» @JacquesLucke I am sure, majority of users do not try to achieve exact color, they want to achieve eye-pleasant result.

Also it worked, and worked well.

Just for the future.
Idk if you revert to previous version or fixed it.

Old zone with zero alpha looks this:
image

frames have proper opacity mix and look this:
image

image

zone overlay for some reason is always UNDER frame, which is illogical…

@JacquesLucke , should i report it?

Zones used to be drawn behind frames, and that was a bug. The fix for that caused the issue in this bug report. The fix I committed earlier today makes it so that frame labels are always drawn on top so they are not hidden by other zones (or frames for that matter).

What kind of issues appear with transparency? What is «tricky theming?»

The tricky thing is that different kinds of zones have different colors which would mix to all kinds of other colors if they had transparency (especially with nested zones). However, the color is also used to communicate what kind of zone it is, so mixing the zone colors makes that kind of useless.

Okay, that`s reasonable

However, the color is also used to communicate what kind of zone it is, so mixing the zone colors makes that kind of useless.

Oh, I see. I did not think about nested zones. So the border should be opaque, and for zone it is preferable to have alpha noticeably higher than 50% so top color can cover others.

Do you need help with design of this case?
