Created attachment 219999 [details] Workshop basics blank screen in eclipse SDK FreeBSD-12.1p10 Eclipse install and runs. However, when any of the instruction topics (Workbench basics, Java development, Eclipse plug-in development) are opened all that displays ia blank grey window with what appears to be a progress bar in the lower right which does not show any activity. Steps to reproduce: 1. Open eclipse, Welcome window displays. 2. From Welcome window select Workbench basics. 3. Results expected - Workbench basics window opens with text. 4. Results observed - Empty window opens, see attachment. When run from CLI the following is recorded: [root@vhost01 ~ (master)]# eclipse 2020-11-26 08:58:51.110:INFO::Start Help Server: Logging initialized @110599ms to org.eclipse.jetty.util.log.StdErrLog 2020-11-26 08:58:51.266:INFO:oejs.session:Start Help Server: DefaultSessionIdManager workerName=node0 2020-11-26 08:58:51.266:INFO:oejs.session:Start Help Server: No SessionScavenger set, using defaults 2020-11-26 08:58:51.267:INFO:oejs.session:Start Help Server: node0 Scavenging every 660000ms 2020-11-26 08:58:51.306:INFO:oejs.session:Start Help Server: node0 Scavenging every 726000ms SWT call to Webkit timed out after 100ms. No return value will be provided. Possible reasons: 1) Problem: Your javascript needs more than 100ms to execute. Solution: Don't run such javascript, it blocks Eclipse's UI. SWT currently allows such code to complete, but this error is thrown and the return value of execute()/evalute() will be false/null. 2) However, if you believe that your application should execute as expected (in under100 ms), then it might be a deadlock in SWT/Browser/webkit2 logic. I.e, it might be a bug in SWT (e.g this does not occur on Windows/Cocoa, but occurs on Linux). If you believe it to be a bug in SWT, then Please report this issue *with steps to reproduce* via:

There's an underlying bug with webkit2-gtk3 port that has dogged the eclipse port for a long, long time. It still has not been resolved correctly. Some workarounds have been put in place in webkit2-gtk3 2.30.1_2; but the core problem has yet to be resolved. TLDR; it's webkit2-gtk3 that needs to be fixed, not Eclipse.
4.33 work fine on 14.1 amd64. Test please new version and write here if you still have this error.
