On about 10 models, where we've created "tab" like buttons using shapes to allow users to control what visuals they see, we stack buttons up against each other and have since the new shapes came out. Users click the blue "buttons" to see different visuals and a white tab will then show.
We're now on. [Version: 2.98.683.0 64-bit (October 2021)].
What we've seen is that the shapes "degrade" where the left-most shape loses it's left edge. This is true for most but not all models and most but not all shapes. Strange. Here's an example of what a "tab string" starts out looking like.
And here's an example after degradation. You can see the shape has lost it's left edge
I've fixed all of them already once...and it's re-occured. It has degraded on both desktop and power bi services.
