ODS file to reproduce the bug

In the attached ODS file, the smoothed line is not drawn correcly here with LO on Fedora 20: the line is full of weird white shapes. If I disable the Display -> Enable smoothing global LO option, the line is correct. Same if I disable the smoothing when choosing line type in the graph preferences.

Is this specific to my configuration? I have an Intel Ironlake Mobile GPU ("intel" X.org driver).

Unable to repro. Maybe Linux or system specific?

It would be interesting to hear whether somebody else on Linux but with a different GPU sees the same bug.
Comment 3 Buovjaga 2014-11-09 15:02:10 UTC
Bingo! On Manjaro KDE the blue line is messed up with white artifacts.

Info: Gallium 0.4 on AMD RV620.

Build ID: Arch Linux build-1

Windows was fine.
