Bug Description

Some of the sky images are severely incorrectly distorted at some of the sky coordinates. The attachments explain everything. It may not be easy to spot the problem with a normal square nebula/planet texture. So I made a transparent image with 'Stellarium' written on it.

If the problem is not easily noticed, drag around the sky a bit, and you might chance upon that easily. Most often, I've noticed the incorrect distortion while the image is moved towards the centre of the screen, though I'm not very sure on the problem characteristic.

I also have the equatorial grid for reference. When the image is loaded with loadSkyImage() it must be distorted according to the equaotorial refernce frame.

Normally distorted per the equatorial grid

You can notice the problem at around 'l', 'a' and 'r'

Notice the problem around 'e'. I havn't noted down the sky coordinates, as it seems the problem depends more on the positioning on the screen , than at a sky coordinate

Without the grid.

The test image.

Changed in stellarium:
status: New → Confirmed
importance: Undecided → Medium
