[Bug 1796457] [NEW] Compiz Crashed with SIGSEGV [Radeon]

 

Public bug reported:

Symptoms:
On login, the desktop takes a long time to load, and when it does, everything blinks. It is possible (but difficult) to open a terminal and execute commands, through the right-click desktop menu.

I first noticed the issue in mid-July of 2018.

System:
Acer 5100
Ubuntu 16.04 (64-bit)
Graphics card: VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS482M [Mobility Radeon Xpress 200]

Possible red herring:
Believed to be mesa-related, as symptoms very similar to bug #1741447 and #1735594. I have been informed by a mesa developer that my issue is different because that bug affects Intel GPUs. This system has a Radeon GPU. Ubuntu reports it as a Compiz issue, so best to begin from there?

Note to developers: log files are as attached to bug #1795709. That bug
was declared invalid by Apport because it says I don't have the
necessary debug packages installed. However, I could not find the debug
packages in the repository, so that is why I am submitting this report
manually. Please tell me what you need and I will upload logs as
required.

Many thanks for any help.
