When adding a vector layer (polygons) in EPSG:4326, project has CRS EPSG:3857 and OTF CRS transformations are enabled, on some scales (mostly when zooming out) the layer features are invisible.
This also happens with other project CRS, but seems to be worse with EPSG:3857
Also, when using a vector layer of global coverage, on some scales the polygons are distorted and many are invisible.
This does not happen in QGIS 2.2 so is probably related to MTR.
attached files shot1-3.jpg are screenshots showing various zoom levels with file tmp1.zip loaded (single polygon), and polygon is invisible in some levels but is within map extent.
attached file shot4-5.jpg are screenshots showing various zoom levels with file tmp2.zip loaded (many polygons, global coverage), on one zoom levels polygons are ok, when zooming out some features are invisible.
