I've identified a new issue with texture rendering. It's occuring since less than a week with my builds from CVS. Each time I restart Celestia, the Earth is having some textures problems as shown below. The problem seems to go away if I move a bit around Earth, so it's not a permanent problem under a single session. The shape of the "wrong patch" is variable with each launch and appears to be correlated with Earth's rotation relative to the date and time.
I'm also experiencing a similar problem with Jupiter, which is showing some patches full of stars, the first time I see the planet after each Celestia restart. As soon as I move around, the problem disappears. This problem seems to be related to the texture loading.
I'm using a 4k PNG texture for the Earth and a 4k DDS texture for Jupiter. Both are using a cloud layer. I can't tell if this is related to the problem.
Anyone able to confirm this ?
