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

 

I have tested this on four different systems:
* Two with ATI video cards using fglrx, both of them had this issue, comment 4 also mentioned fglrx
* One with ATI video card using the opensource Xorg driver, it's not affected
* One with Intel video card using the opensource driver, and it's not affected.
I haven't had the chance to test this on NVidia cards, but it seems to me that this can only be experienced when using fglrx (the binary ATI video card driver). If anyone can reproduce this on non-fglrx, please comment here, to know that it's not an fglrx-only problem.

Title:
  Graphical errors on charts in resources tab (faded bands)

Status in “gnome-system-monitor” package in Ubuntu:
  Confirmed

Bug description:
  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. 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.

  Ubuntu release: Oneiric 11.10, x86_64
  gnome-system-monitor: 3.2.0-0ubuntu1
