Flickering text alignment bug

Problem:
I’m getting odd flickering text on some captions.
The example below is on a loop, but in the real thing this alignment movement happens only once a few seconds after the project loads.
It happens on multiple slides even if I delete the textbox and recreate it.

See below:

ActivePresenter Version: Required. 8

OS: Required. Windows 10

Hi,

Are you using Embed Fonts options when exporting to HTML5?
If so, the browser will render the text temporarily with a local font until the embedded font is loaded.
It may cause this issue (if two fonts are quite different) when the browser renders the text again with the embedded font.

Regards
