KeePassX GUI rendering empty in Ubuntu Gnome 15.10

[Maximilian bloch]

KeePassX GUI often does not render, making it unusable (see attached screenshot). This is hard to reproduce, as sometimes it works and sometimes it doesn't. A fresh reboot remedies the issue, but after a while something unknown to me makes it break and once the GUI renders empty, it becomes reproducible.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem. It's not related only to KeePassX and Ubuntu 15.10. I have the same problem also with ownCloud sync client and I run Ubuntu 14.04.

I think this issue is related to (or a duplicate of) https://bugs.launchpad.net/ubuntu/+source/unity-settings-daemon/+bug/1510899.

As mentioned in the commends of bug #1510899 the solution of supplying QT_GRAPHICSSYSTEM=native on the command line followed by keepassx "fixed" the issue temporarily.

> QT_GRAPHICSSYSTEM=native keepassx

Runs and renders it properly.

I can confirm the quick fix of running 'QT_GRAPHICSSYSTEM=native keepassx' on the command line, for a single working instance of keepassx.

For a more sustainable fix, adding 'QT_GRAPHICSSYSTEM=native' to /etc/environment works for all subsequent instances of any effected gui, taken from http://askubuntu.com/a/694276/75991

This root of the issue seems to be with JAVA. I was able to reproduce the issue by simply opening a JAVA dependent program like PHPStorm. I have read about this being fixed with openjdk-8-jre, but I haven't tried that.

I confirm that this bug still happens on current Ubuntu 16.04 with KeepassX 2.0.2. Openjdk-8 does not fix it. Using QT_GRAPHICSSYSTEM=native still works.
