Style Editor - Why do Pseudo Instances flicker in Properties?

Description

Video

Pseudo Instances seems to be a term from the Style Instances. Sort of in the same way, you’d probably see before and after in CSS.

Pseudo Instances used to show up in the Explorer though, I don’t know why they’re invisible now. They show up in the Properties Panel instead.

However, everytime a Pseudo Instance has their value changes (such as Color), it will re-appear in the Properties Panel.

Not sure why, but I am curious. This makes me wonder whether one should for instance, animate a Style Sheet, that uses Pseudo Instances or not. Are there any consequences in performance? :thinking:

Re-production Steps

See video attached in the Private Message

  • You select the Instance that is being “selected” and affected by the Style Sheet

  • It needs a Pseudo Instance so it appears in the properties panel, like so
    image

  • Then just modify the Pseudo Instance, a good way to see this issue, is by modifying Color, like a gradient.

Expected Result

That at least, it doesn’t change the scrollbar’s position?

Actual Result

The Pseudo Instance flickers in the Properties Panel. But what else does that mean?

Hi, thanks for the report!

For the question regarding performance of animating a pseudoinstance property vs. animating a styled property on an actual instance, the performance impact should be minimal and we would not discourage animating a pseudoinstance property. The flickering is getting triggered by a StyleRule property update (occurs for both pseudoinstances and actual instance properties) which recreates the PseudoInstance section UI, so this is more of a bug with the PropertiesPanel PseudoInstances section itself.

Unfortunately, due to a large number of higher priority forum bugs, we will be unable to resolve this issue in a reasonable timeframe. Instead of keeping this issue open indefinitely, we are closing this report. We appreciate your patience and understanding!
