Noticed this testing the Photon RC3 Java EPP package under Ubuntu 8.4 on Wayland: When I click through a couple of tips, Ubuntu's crash reporer (apport) pops up, telling me that Webkit crashed. Interestingly, the browser widget within the Tips dialog seesm unaffected, but the Welcome view, which previously showed its usual content in the window behind the Tip of the Day dialog, is now blank. From /var/log/apport.log: ERROR: apport (pid 7421) Sat Jun 9 16:40:05 2018: wrote report /var/crash/_usr_lib_x86_64-linux-gnu_webkit2gtk-4.0_WebKitWebProcess.1000.crash ERROR: apport (pid 8710) Sat Jun 9 16:46:30 2018: called for pid 7723, signal 11, core limit 0, dump mode 1 ERROR: apport (pid 8710) Sat Jun 9 16:46:30 2018: executable: /usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitWebProcess (command line "/usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/WebKitWebProcess 3 50") ERROR: apport (pid 8710) Sat Jun 9 16:46:30 2018: debug: session gdbus call: (true,)
Created attachment 274413 [details] Screenshot illustrating the situation I think I can refine my steps to reproduce: - Click "Next tips" a couple of times until several "Unknown" processes have accumulated in the Ubuntu dock (Bug 535739). The Welcome view in the background looks still fine. - Close the Tip of the Day dialog The Welcome view becomes blank (see screenshot) - Close the Welcome view by clicking on the view's X.

(In reply to Andreas Sewe from comment #0) > Noticed this testing the Photon RC3 Java EPP package under Ubuntu 8.4 on I take it you mean ubuntu 18 rather than 8? Might be because of: 532340 – [Gtk] Frozen UI opening a shell on Ubuntu 16.04 LTS, but works 17.10. https://bugs.eclipse.org/bugs/show_bug.cgi?id=532340 Can you list your gtk and webkit versions?
btw, does this happen with x11 backend? Can you post your webkitgtk and gtk lib versions?
Andreas you can do sudo dpkg -l > config.txt to list all your installed packages with versions.

Thanks, you have webkit2.20 and gtk3.22 (which are the newest). I'll try to reproduce the issue on my system. But I also have a suspicion as to what could be causing the crash. Btw, are you able to test with a child eclipse? If I can't reproduce the issue, would you be able to test with a gerrit patch to verify a bugfix?

Would the contents of /var/crash/_usr_lib_x86_64-linux-gnu_webkit2gtk-4.0_WebKitWebProcess.1000.crash (mentioned in comment 0) help to confirm your suspicion? If so, I can attach crash report as well. > Btw, are you able to test with a child eclipse? > If I can't reproduce the issue, would you be able to test with a gerrit > patch to verify a bugfix? Yes, I am willing to test this with a runtime Eclipse, although I would need some pointers as to how to set up an Eclipse to compile (the necessary parts of) Platform. Last time I looked it was a bit more complicated than just installing the Platform project via Oomph. :-(
Should be fixed by this guy: https://git.eclipse.org/r/#/c/125270/ Please test with builds from next week & re-open with new stack trace if issue still occurs.
