Playwright Browser Steps / Visual Filter Selector Completely Black

[flyerbear]

I'm trying to do change detection using the Playwright Chromium browser on some javascript dynamically-generated websites, but whenever I run it, both the "Browser Steps" and "Visual Filter Selector" just show a black page on certain websites but work fine on others. However, if I back out and go to the "Preview" of the watch, both the Text and Screenshot are correctly populated with text and a screenshot of the offending sites, respectively.

Below the "Visual Filter Selector" screenshot it says "Currently: Loading..." pretty much indefinitely.

I'm running v0.40.3. I've installed Playwright according to the docker-compose instructions on the wiki, and selected Playwright Chromium/Javascript on the Request tab as below.

I've also tried modifying the "Wait seconds before extracting text" to 5, 10, 20, and 60 seconds but the result is the same.

Why does the browser request work for the routine checks but not during watch setup? Is this an issue or (more likely) what am I screwing up? Any help would be much appreciated!
