[Bug 881172] Re: Graphical errors on charts in resources tab (faded bands)

 

** Attachment added: "Screenshot showing the issues"
   https://bugs.launchpad.net/bugs/881172/+attachment/2571065/+files/system-monitor-graphical-issues.png

** Description changed:

  On my system, the charts on the system monitor resources tab are
  displayed with some graphical errors.
  
  The most obvious manifestation seems to be faded bands along the charted
  lines, though there is also extra white around the chart area (rather
  than the grey of the window background). The chart labels also end up
  quite blurry and hard to read. Sometimes the pink line for memory usage
  seems to hover horizontally right in one of the faded areas, and becomes
  nearly invisible.
  
- Bizarrely, the problem is sometimes only present on one of my monitors
- than the other. The screenshot I have attached was taken straddling the
- two monitors; the zone on the left appears normal, while the zone on the
- right is noticeably affected. Dragging the system monitor between the
- two monitors causes the issue to appear and disappear. However, other
- times there is no difference and the system monitor is affected equally
- no matter which monitor it is on.
