I recently installed X3AP for Linux (through steam).
Everything in the game seems to be working well (thus far) but I seem to have a big issue with what I assume to be some textures; specifically the clouds textures on all planets and what I assume to be some sort of semi-transparent "glare" texture when looking at remote stars.
Screenshots, planet issue:

"Glare" issue:

I assume the root cause is the same for both.
My system information: Debian Jessie amd64; NVidia Geforce 660M (and also an intel card, running the game through it has the same issue, see below).
The game is the very latest steam version, unmodded. The bonus pack is installed (through innoextract due to the lack of a linux port).
My graphic drivers are also the very latest, proprietary nvidia ones (the 9th February 361.28 release); installed in an attempt at fixing the issue - was previously using ~6 months old drivers with the same issue.
What I have tried:
- Changing all graphics parameters (including the greyed out AA one through config.yaml, resolution, glow, etc.); running the game windowed as well; to no effect.
- Updating my graphic drivers (no results).
- Starting a new game with a different start script (the screenshots above come from a Humble Merchant one) - no result.
- Checking the files integrity in steam (everything OK, no anomaly).
- Running the game through my Intel card (I have optimus) instead of the nvidia one; the game runs fine but has the same issue.
- Checking the "Run previous version" checkbox.
- Launching the game directly with steam closed (still going through testandlaunch).
- Launching X3AP_main and X3AP_main_b11 (I assume this stands for "build11") directly without going through the config tool first (with or without going through testandlaunch).
- Out of despair, I also tried tweaking LD_LIBRARY_PATH to use some system libraries instead of the steam/game ones (tried that for libGL* libs such as libGLEW) - no results either.
- Launching X3TC without AP; same issue.
The fact that the issue occurs even with the intel card makes me suspect some sort of texture compression issue, perhaps ? note that in some systems, the planet looks mostly OK but a slight upper cloud layer is messed up the same way - weird lines instead of clear texture.
Also note on the above screenshots that on most planets, only part of the planet shows the issue.
I should also add that I played X3: Reunion years ago (the LGP preorder boxset - also participated in the LGP beta at the time) and I never saw such an issue through hundreds of hours of game time - this probably has low relevance though, since I suppose X3TC/AP improved on the graphics and the issue probably occurs on one of those improvements ?
In any case, this is a big issue for me because it completely breaks immersion; I'm also afraid some other texture issues will show up later in game (I only played for about an hour right now - no combat, for example). I was ecstatic when I discovered that X3TC not only was released for Linux, but that X3AP had been released as well, and I'd really like to be able to play this game.
Does anyone have any suggestion / tweaks I could try, or an idea of where this issue could come from ? even some sort of graphics improval mod that would replace those textures may be a solution, maybe ? or possibly converting the problematic texture to another format that the game could understand as well ?
Thanks in advance !
[Edit] Forgot to add, I also tried searching for similar issues on Google to no effect; and also tried looking through this very topic for similar issues with no results either (a "search topic" feature on this forum would be a great addition, by the way). Finally, I also looked extensively through the game log (stdout & stderr) but nothing seems out of order - no "unable to load texture" or really any error message that seems relevant.
[Edit2] Updated my forum profile to link to my steam account to prove ownership of the games in case this is required.
[Edit3] I have performed a more extensive search on the forums and it seems to be the exact same issue as another forum user, Gligli, reported previously: http://forum.egosoft.com/viewtopic.php? ... 68#4482968; however, there was never any follow up. I did send a PM to that user just in case. At least I know I'm not alone !
