Doesn't seem to work in 2025.1 on MacOS

[dannybloe]

At least in version Build #WS-251.23774.114, built on March 13, 2025.

I just have an empty tab when opening a new or existing diagram.

Cheers,

Danny

UPDATE: Workaround:

Click IDE main menu Help | Edit Custom VM Options, add -Dide.browser.jcef.out-of-process.enabled=false on the new line, restart the IDE.

Can reproduce on my Mac 15. Plugin version 0.2.6, IDEA same build as above(only .xxx part differ)

I see a blank rendered frame:

Same here with (MacOS Sequoia 15.4.1, IntelliJ IDEA 2025.1). If I start the IDE I can open an regular (non diagrams.net) SVG and it will be rendered (in splitscreen and image mode). However, if i then open a diagrams.net SVG (or PNG) that one does not render and if I reopen the regular SVG it won't render anymore either (have to restart the IDE for that). Hope you can sort it out, really miss this plugin. If you need more information, just let me know. Has been working fine before, i think it is related the IntelliJ update, because my ExcaliDraw plugin is now having the same problems.

Update: After opening a diagrams.net SVG my AsciiDoc plugin rendering will be broken too (until I restart the IDE)

Message from upstream JetBrains issue:

Fixing this issue and testing it to release may not be in time for the release of 2025.1.1 (2025.1.1 will be released next week), so the fix of this issue will be delayed. You can use the temporary solution in the problem description first, and we will update this list when we fix this problem.

[bliet]

Does not work with 2025.1.1.

[Les-Fleming]

Workaround works for me in version 2025.1.1.1 Ultimate Edition

[aGitForEveryone]

Can confirm that the workaround works in Pycharm 2025.1.1.1:

Workaround: Click IDE main menu Help | Edit Custom VM Options, add -Dide.browser.jcef.out-of-process.enabled=false on the new line, restart the IDE.

[thomaseyde]

Does not work in 2025.1.3 on Mac. Fixed with workaround:

Click IDE main menu Help | Edit Custom VM Options, add -Dide.browser.jcef.out-of-process.enabled=false on the new line, restart the IDE.

[acltabontabon]

Click IDE main menu Help | Edit Custom VM Options, add -Dide.browser.jcef.out-of-process.enabled=false on the new line, restart the IDE.

Nice, thanks for the workaround - works for me.

Intellij IDEA Ultimate: 2025.1.3 (Mac)

[louiedgomez]

It worked, had to restart the IDE entirely not just close. Rider 2025.1.4 (Mac)

[ahus1]

The underlying issue is marked by JetBrains to be resolved since 2025.2 EAP 6

Anyone running Mac and 2025.2 to confirm that this is now working without the workaround?

Thanks!

[nealio82]

I can confirm that it does not work on 2025.2 (GA) with the workaround removed

~~Works for me without workaround after upgrading to 2025.2.1. Did not work on my previous version, 2025.1.2~~

Strangely, it worked exactly once after updating. It has returned to non-functionality, though the workaround still works
