HTML Layers delay #8320

Open Dramamini opened 2 days ago

Dramamini commented 2 days ago

When I change layout, if second layout has HTML Layers, they are drawn with a significant delay.

HtmlLayersDelay.zip

Steps to reproduce

  1. Run Project in fullscreen (to see the problem more clearly)
  2. Change layout

Observed result

Html layers are drawn one after another with a delay

Expected result

To see all the layers drawn at the same time (even if layout takes a little bit longer to load)

More details

The upper layer is drawn last even if it is a non html layer

Chrome, Windows

As with #8321 it looks like turning off worker mode works around this. However I'm not sure why it doesn't update all the content simultaneously in worker mode - I'll look in to that.

Hi Ashley! Thank you very much for your time to look into that. I tried to turn off worker mode and indeed it's a workaround!

But for issue #8321 isn't working. (I found a workaround for textbox not to show up before layout starts: I keep it invisible and make visible at the first tick using "trigger once". The problem is that at the end of the layout, text box disappears faster than the layout with a noticeable difference and this isn't fixed with worker mode off.)

Thank you very much again. Congratulations for your amazing work.
