Description
Plugin layers are not drawn correctly when rotation is non-zero. (Tried with Crayfish, probably OpenLayers will have the problem too)

It might be easier to split this into one ticket for each non-working plugin as I'm afraid it needs special handling in each of them.
If the problem is (as I supposed without looking) in the MapCanvasItem's setRect function, we know there's no way to retain backward compatibility of that method in presence of rotation (problem being assumption of top-left corner of visible extent falling exactly on the top-left corner of the device output, while with rotation active we can only have a fixed corrispondence between centers, not corners).

Replicated, layers from OpenLayers plugin are not rotated on qgis master.

Could you give instruction to reproduce this ?
I've tried "OpenLayers Plugin" (from sourcepole) but I've only found a way to download data and import it into a spatialite db.

Figured out. I'll file a separate ticket for the openlayers case.

Actually, I think plugin related issues should be handled by plugins themselves.
The OpenLayers plugin already has a ticket for handling rotation (feature request): #12666
I've filed another one for crayfish: https://github.com/lutraconsulting/qgis-crayfish-plugin/issues/126
Feel free to reopen if you see an issue with qgis itself, rather than a lack of support by calling code.
