Created attachment 283408 [details] Screenshot 4.17, I20200615-1800 Mac OS dark theme. 1. Launch runtime eclipse workbench (child/inner eclipse) from main Eclipse which is using light theme. 2. Switch theme of runtime eclipse to light. 3. Restart. Even after a restart, the theme is corrupted in the runtime eclipse. See attached screenshot. I have tried the following JDKs to launch the runtime eclipse: - openjdk-14_osx-x64 - corrupted - jdk-11.0.6.jdk (oracle) - corrupted - openjdk-11.0.2_osx-x64 - works fine
I see this problem with openjdk-15-ea+28 also.
Tested I20200825-1800 using jdk-11.0.6.jdk (oracle) and openjdk-15-b36. The issue is still present.
Not sure whether this belongs to swt though. From the screen shot I see that the background for the image is set properly. @lars, Can you please help us here?

Ok, Do you know where the background colors are set when we change the theme?
(In reply to Sravan Kumar Lakkimsetti from comment #5) > Ok, Do you know where the background colors are set when we change the theme? Anything in the error log? Like widget is disposed? If I understand this issue correctly, this also happens with a restart of the runtime IDE. We do have a CSS handler for setting the background color, I'm currently working for a customer and cannot look it up. I can check after work tonight, if desired.
Since this happens only in the runtime workbench, I consider this low priority. There are no errors in the console or error logs. Mostly I see issue with setting of background color. When ever you have time please let me know where I can look for css handler.
Sorry for the delayed response, as I said working for a client, hence I can also very restricted look into Eclipse code. The responsible handler for setting the background color should be: org.eclipse.e4.ui.css.swt.properties.css2.CSSPropertyBackgroundSWTHandler
I see the same issue with 4.20 RC2 build I20210603-0040 on using openjdk-16. As I work with the light theme (even while debugging in the runtime workbench), this bug does not allow me to use a JDK after openjdk-11.0.2 for launching my runtime configuration. Any workarounds until this is fixed?
Seems like it is related to https://bugs.eclipse.org/bugs/show_bug.cgi?id=575960. Interestingly, it also happens in an RCP app I'm developing (see https://github.com/gama-platform/gama/issues/3193).
