Artefacts with rubber band

Description

I witnessed artefacts while measuring and digitizing. I think these functions are based on rubber band.

Interestingly, I could not reproduce the artefacts in a Windows-Virtualbox on the same machine, so it doesn't seem like the graphics driver is causing that.

Rubber band artefacts

I cannot see this with gnome (Ubuntu).

lutra: I suppose Karmic or older? It's working perfectly fine there.

It's obviously a regression from Qt 4.5 to 4.6. Ubuntu Lucid ships Qt 4.6 and the artefacts are there. Same with Qt 4.6 and 4.7 in Fedora.

It is not linked with the graphics driver or the window manager.

also reproducable on debian unstable (Qt 4.6.3)

Platform: Fedora → Linux

odd, I cannot set them on Lucid using gnome using the measure line and area tools, but they show using the measure angle tool.

Could you please test with r14234? It fixes the artifacts on my system (but could be different depending on window manager, OS, etc.)

Brilliant, the artefacts are gone for Qt 4.6.3 and KWin. Haven't tested other versions yet.
