JCEF Preview not rendered on Windows 10

The preview is not rendered in real time even for simple asciidoc files. This issue started a few weeks ago, but I can’t be sure if it started right from the 2020.1 release of Intellij or sometime later.

The PDF or HTML export and other functions work just fine, but the preview is never rendered. On the IDE logs (idea.log) I find this line every time I open an adoc file:

2020-09-01 17:08:41,437 [5973502]   WARN - tor.jcef.AsciiDocJCEFHtmlPanel - rendering didn't complete in time, might be slow or broken 

The minimal example is just a new project with an adoc file in it:

I have tried multiple things like uninstalling the plugin and cleaning the cache but the problem even persisted after upgrading Intellij from 2020.1 to 2020.2 and currently in 2020.2.1.

Thank you for testing this again. I promoted 0.31.33 to a regular release and it is now rolling out to all users.

I opened an upstream issue https://youtrack.jetbrains.com/issue/IDEA-252128 as this affects other plugins as well; let’s see how this is handled upstream.

Thank you for sending the log file. I searched it for clues, but haven’t found a clue yet. I tested it locally with Windows 10, also a second screen, but wasn’t able to reproduce the issue you experienced.

When I run my IDE on windows, I see some JCEF helper processes. Do you see them as well (or do you see error messages related to them)?

I noticed that you have a non-ASCII home directory: “C:\Users\AndréGomes”. Now and then I’ve seen errors with JRuby (see here), but this doesn’t affect your preview. And you reported your preview works find with JavaFX.

As you experienced problems with the Markdown plugin, it might suffer the from the same cause. May I suggest you open an issue with JetBrains describing your problems with the Markdown plugin? If there’s a bug within JCEF, and if they find and fix it for Markdown, they will fix it for the AsciiDoc plugin as well. Please post the link to the issue in this ticket so people can upvote it.
