Broken: version 2.93
Worked: Never (2.8+)

Short description of error

Using viewport visibility as a driver from another object doesn't works unless you constantly hit "update dependencies" it in the driver property.

For this, i used the cube's visibility as a driver on the shape key of the sphere.
The not working file.blend
In the outliner, enable the viewport visibility for the cube, then disable it again. The shape key doesnt update unless you go into the driver property and hit the update dependency button.

The working one.blend
This is what i was hoping it would do. The only way I could use viewport visibility as a driver is to use a custom property on that object then use the custom property as a proxy.

Is there a reason why it dont update if you use visibility as a driver from another object or is that a bug?

Steps to reproduce
The not working file.blend

Open file
Click on Disable in Viewports icon on Cube object in outliner
Sphere shape should be change, but it doesn't

This sounds like #78071, but checking with 3.0 I can't reproduce the problem.

Please check if this issue happens with latest alpha build from https://builder.blender.org/download/daily/.

@iss It doesn't work in the alpha or the candidates. I recreated it in the alpha and it still doesnt work. Did you try the first file i uploaded?

@iss #78071 yea it's the same. The project file from that ticket doesn't work in 3.0 c53ffda8a4 either. I disabled cube_1 but it dont set off the modifier on cube_2 unless you update it in the driver property

I re-checked and I was able to reproduce the bug here. Not sure what I did to make it work, but it did even if I reload the file.

In any case I will mege this with #78071 since this seems to be same issue.

@iss The ticket that this got merged with was made over a year ago and the guy that was working on it said to make a new bug report because it was closed for so long. Should this get merged to that ticket?

I saw it was still open so I merged. I can reopen this ticket just in case T7807 is considered resolved already despite it's current status.

I think it's not really the place for this but here's a workaround for this annoying bug:

create a keyframe for the driver hide_viewport flag and all will work properly ;)

Happy blending !
