[Qgis-developer] QGIS 2.10 - weird black circles

[kimaidou]

Hi all,

When playing around with projects from 2.8 to 2.10, some users reported me
they encounter weird rendering of their layers. Some black circles are
drawn on top of the layers, like in this image [1]

This happens for point or polygons, and for different method (
classification, single symbol, etc.).

I can manage sometime to get rid of these circles by opening/closing the
layer properties dialog, and checking on/off the layer in the legend.

Anyone has already seen this, and found a solution ? It seems to me it is
related to conversion of old project with 2.10, but I am not sure

Any help appreciated.

Michaël
