Description
For a polygon layer using a "Simple fill" style, the outline has bevelled corners, except that the start/end point is drawn as if it was a polyline - the two edges do not meet. See the attached screenshot.

I mean it draws two lines ending at the start/end point, rather than drawing a bevelled corner.

I am unable to see the image, it seems broken.
Anyway valid polygons should be made from linear rings, i.e. polylines where the first and last coordinates are the same. This may be the source of the problem in your case, so the outline is not drawn properly.
Probably the only correct thing to do is to fix your data: we have to avoid checking of validity of geometries as it would slow the rendering significantly (there may be other validity problems, some are handled fine by rendering functions, others not).

Oh, sorry, it was a tif after all (But I was sure I checked it displayed in my browser...)# file corners.png

Here's a png.

That isn't the problem here... or at least, if it is, then is all polygons created by the digitising tool are magically invalid :)

Hello, bug triage...
I am not able to reproduce this with QGIS 2.13 master. You can set the join style for the Simple Fill outline and with whatever option, the rendering is correct.
I am closing this bug.
