There are several different items that are not displayed at all (Blank Boxes). This includes hover-help, JavaDocs tab, Welcome Page, Tip of the Day…seems to be widespread. I thought it was my initial dev environment but I created a new one (fresh install of Ubuntu/Eclipse) and the problem persists. Current setup:
– Ubuntu 22.04
– Eclipse 2022-03 (4.23.0)

Scott,

Sorry that you are seeing this issue with Darkest Dark theme. Thank you for the details and the screenshots.
I ran a quick check on Ubuntu 22.04 and Eclipse 2022-03 but could not replicate the reported issues. We will continue to test this further.

Can you please check how it works in Eclipse Dark theme? Go to Window > Preferences > General > Appearance, select ‘Dark’ instead of DevStyle Theme.
Do you have any particular OS theme set?

Apologies for inconvenience caused.

Thanks for the quick response.

Tried a couple more things:
– Switched to “Dark” instead of DevStyle…problem is still there, blank welcome screen etc.
– Uninstalled DevStyle…problem is gone, windows appear normal

Thx

Scott,

Do you see the issue in a fresh new workspace as well?
Also please share the current Ubuntu theme details. If you change the theme to say, Adwaita, does it help?

– Problem persists with new workspace
– Problem persists different Ubuntu Themes.

I have output from eclipse starting in “Verbose” mode. Looks like exceptions are being thrown on startup only when DevStyle installed. Multiple “java.lang.Error: SWT Resource was not properly disposed” errors logged.

Full output attached for with/without DevStyle installed. Same workspace is being opened for both runs.

Thx.

I also have the same problem, also it doesn’t show when I click on Show in JavaDoc view, before set up the plugin, the javadoc box was working. (in debian buster)

now my javadoc works, but I had to reinstall the ide and download a src.zip folder (sudo apt install openjdk-11-source) and reinstall the darkest dark plugin without the codetogether bundle, everything is fine now, I answer this in case someone encounters the same problem, maybe this works for them

[ordiel]

Same problem here, for now I have to stop using Darkest Dark due to this (it gets fixed when removed). Is there any update on it?

[support-swapna]

I ran fresh tests on Ubuntu 22.04 but could not replicate the problem. We are actively investigating this issue.

@lykkos and @ordiel : Can you please share the IDE and OS version details and the .log file located at workspace dir/.metadata/.log (rename it to .txt and attach it here)

There seems to be an issue with Wayland, the default window-manager in Ubuntu 22.04. By disabling it and switching back to X11 the issue is gone and the HTML-rendering Eclipse-Components are working with the DevStyle-Themes again as expected.

Regarding the bug:
As @scott_hargreaves already pointed out, not only the JavaDoc-PopUp is affected. All HTML-rendering components (the whole JavaDoc-View, Help- and Welcome-Pages, the internal webbrowser, …) do not work as expected: The displayed content is rendered – you can select + copy/paste it – but the background-layer (in the selected theme-color) makes the content invisible by being rendered in front of the content.

I face the same problem on Ubuntu 22.10 under Wayland. As @olaf123 mentioned every single HTML component is broken. Steps to reproduce:

* Install Ubuntu 22.10.
* Install epiphany-browser to pull in the WebKit GTK libraries that Eclipse needs.
* Download and run Eclipse Installer 2022-12 R. I used JDK 19 and installed the standard Java edition of the IDE. At this point everything worked as expected, there are no issues with the JavaDoc popups.
* Install the DevStyle theme plugin.

The only workaround that I could find other than rolling back to X11 was to export WEBKIT_DISABLE_COMPOSITING_MODE=1 before running Eclipse.

@vchernyshev,

Thank you for sharing the reproduction steps and the workaround details.
I could replicate the problem on Ubuntu 22.10 at my end and I have filed a bug report for the dev team to look into it.
We will keep you posted when the fix is out.

Apologies for inconvenience caused.
