Make a polygon.
Fill it with markers.
Move the map slightly. Markers wil dance, changing their position a little bit as ashown in the attached video. This breaks export to tiles.
There was no such behavior in QGis 2.18

  • Status changed from Open to Closed

There is a project setting under Projects->Properties->General->Avoid artifacts when project is rendered as map tiles. With this setting enabled, it will behave as expected for tile export (it was the same for 2.18 as far as I remember).
