When using the rotate feature on a previously created project, all labels disappear. After rotation, if creating a new layer with points, the point's label also does not show up. If making a WKT point with the QuickWKT plugin, the WKT point's label does work. This happened on two separate Windows 7 installs of 2.7.0-3 weekly builds.

Are this two separate issues, right? If yes please file 1 ticket for each issue, thanks.

About the (canvas) map rotation and labels: I cannot confirm. I created a project with labels in qgis 2.6.1, opened it in master an applied a rotation. The labels do show as expected. Please attach a project (with data) to allow replicate the issue.

About the wkt/label issue: I can also create a wkt layer with the quickwkt plugin and give the points a label without issue (without or with canvas rotation). Please add more details (steps) on how replicate the possible issue.

I want to confirm bug reported by Mike. Labeling is working with map rotated only when project CRS is set to WGS 84. In other case, after rotating map labels are placed somewhere in space... It occurs both in main window and map composer. I'm not sure if writing in good place, but I'm new here, sorry.

I can confirm the label issue with map rotation in QGIS and composer.
In EPSG4326 (WGS84) labels show when the map item is rotated. When in EPSG32616 (WGS84/UTM16N)the labels disappear in composer when the map is rotated.

windows 7 x64
version 2.8.1

  • Subject changed from Labels do not show when using new rotation feature. to Labels do not show when rotating map canvas and reprojecting a layer.
  • Category changed from Labelling to Map Canvas
  • OS version deleted (Windows 7)
  • Operating System deleted (Windows)
  • Target version changed from Version 2.8 to Version 2.8.2
  • Status changed from Feedback to Open

So the labels do not show if the map is rotated and the layer reprojected in a CRS different from the project one.
