Description
There seems some resampling going on when requesting a CRS
which the server supports (with enabled OTF):

e.g. QGIS set to EPSG:4326 and requesting an EPSG:4326 image from a
server that supports EPSG:4326.

WMS driver does not automatically switches to
projection requested by QGIS even if it is supported by WMS server.
You have to manually select the right projection when layer is added.
Preferably, the WMS driver should not only to switch to the right
projection, but also automatically
select the most similar projection offered by server if no one exactly
matches. Anybody is aware of an algorithm or ready for use method
doing that?

might #3740 be a duplicate of this?

- Crashes QGIS or corrupts data set to No

I believe choosing the strictly matching projection (if any) is the most urgent (and the simplest) fix. I thought it was already implemented, but maybe I'm wrong.

Hello, bug triage...
on QGIS 2.13 master (and probably in previous versions), the WMS client set the CRS to the common CRS between the project and the WMS server. If my project is in EPSG:2154 and the WMS server have the layer I want to display in this projection, QGIS WMS client will choose EPSG:2154 by default and there is no reprojection.
I am closing this bug.
