            Bug ID: 99236
           Summary: System (seems to) completely freezes when interacting
                    with java swing applications.
           Product: DRI
           Version: DRI git
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: tmp6154@yandex.ru

I'm not completely certain whether it's related to AMD GPU driver or not, but
it's rather strange issue that I can get stable reproduce for.

I'm running a Gentoo system with AMD Radeon RX 480, with git AMD GPU driver and
git version of mesa. When interacting with scrollable JTextAreas in Java Swing
application, I get a stably reproducible issue (100%). Since this affects
multiple java swing applications (e.g. eclipse), including the program I'm
developing at the time, I can attempt to put together a reproducer java app, if
that's needed.

For first 2-3 seconds, mouse cursor moves jittery, then it stops to move at all
and display keeps displaying same frozen state. Nothing appears to work,
including Ctrl+Alt+F1, etc. But despite machine looking completely locked up,
in fact, it's not. I can ssh into it and issue reboot command. During that
time, display doesn't shows any signs of life until the moment when machine
reboots (but I can hear KDE shutdown sound).

This occurs only under JRE8, both icedtea and oracle variants. Under JRE7 issue
doesn't trigger. If memory serves, JRE8 brought improvements to
hardware-accelerated GUI rendering. This is especially strange, since Swing GUI
framework renders it's own GUI widgets.

Considering that even Ctrl+Alt+F1 doesn't work, I suppose problem happens on
kernel level, possibly in AMD GPU driver.
