Bug description:
[Impact]
Icons disappearing after int32 delta time variable overflows in 24
days.
[Test Case]
Run the automated test to simulate what happens after to the timedelta
~24 days of Unity running.
[Regression Potential]
Low - only the datatype is changed and an automated test is included.
---
unity::TimeUtil::TimeDelta is used throughout Unity to compute time
differences in milliseconds between events. Unfortunately, TimeDelta
returns an int value, which can only express differences up to ~ 24
days. So after 24 days of uptime, Unity breaks. The breakage is
described in the comments.
Original description:
This issue, to me, is the same issue as
https://bugs.launchpad.net/ubuntu/+source/unity/+bug/762478. However a poster
on their thinks this is only related to the nvidia graphics driver. I tend to
disagree, nonelethess I am filing a new bug for it. The behavior is the same.
The icons are not showing up in the Unity launcher. When I hover over them I
can read the icon's "name" and clicking on it works. I tried unity --reset,
unity --reset-icons, sudo restart gdm and finally only resetting my entire
system fixed the issue (although the icons are back to their default now --
none of my custom icons are appearing). I do not have an NVIDIA graphics card,
but rather, a built-in Intel one.
