Unfortunately, there isn't much on Welcome's end that can be done to "fix" this.
This strange (and difficult to diagnose) issue is caused by external libraries failing leading to a segfault/error with the WebKitWebView process, which is responsible for rendering the window. On some other software I maintain, another user had a blank screen issue like this, but it was caused by a library named "libc". Bizarrely, the issue went away after their system (16.04) was updated. The "DPI out of range" is just a warning, this isn't the problem. As this is affecting a development build (17.04), please could you try again on a fresh install of 17.04? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1658996 Title: welcome stays empty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-mate-welcome/+bug/1658996/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
