Ah, thanks for that!
I did a bunch of testing last night.
Unfortunately it’s a mixed bag with my project. Strangely, the project (when it was exported with “Position with CSS left/top” left unchecked) was fantastic on every scene on my iPhone X (on both mobile Safari and mobile Chrome). But on both my wife’s MacBook Air and on my MacBook Pro, on Chrome about 70% of the scenes were fantastic, but 30% were really rough and choppy. Thankfully the browser never crashed, but it sure seemed like it was getting close.
Here is a short screen vid showing how bad it was on one of the scenes.
I now remember doing a bunch of testing on this a long time ago and determined at the time that my overall stability was increased by leaving the box checked.
However, I’m bummed that it was so fantastic on mobile and so bad (in only a few scenes) on desktop.
I guess I’m wondering - is there any way to selectively apply this setting to individual scenes or to an individual layout (desktop only, for instance)?
If I could impose “Position with CSS left/top” on only the scenes that need it (and only on desktop), then the whole project would look great! If not, I’m going to have to accept “Position with CSS left/top” as my only option.
Thanks again for your input on this!
