master, intel graphics, troubles with FSAA

[NoQ]

Yay my dreams have come true: i'm finally on integrated intel.

Now, i'm having a trouble running master: i'm seeing lines between map tiles and their triangles when i turn on FSAA (any value).

Well, i don't really care about FSAA, just curious if there's a simple workaround.

Integrated intel ? My crystal ball shows more nightmares for you.

Seems it is driver issues, you using mesa, or is this wintel ?

Ah i forgot to say everything

By the way the rest is running pretty well out of the box. It's much more pleasant than stumbling into continuous troubles with ATI.

I remember this strange issue happened to Warzone years ago. Can not remember which type of gfx card and gfx driver I used. Today I use an Intel HD4000 integrated chipset too, but it looks okay.

[Per]

I had Intel integrated for a bit a few weeks ago (until I had to switch to Nvidia again to support my new monitor), and it seemed to work quite fine. I do not know if I had FSAA on or not, though. Intel drivers have come a very long way the last few years, and are now quite decent and even somewhat capable.

It may be an issue with the terrain rendering. I have seen problems like that before. They usually only crop up when you use higher levels of AA. Something about how the tiles do not line up properly and it affects how the textures are rendered.

Never run across it myself, but I have seen screeshots of those who have.

Doubtful.
As a general rule, if it looks OK on AMD & Nvidia, but not XYZ, then the issue is pretty much always XYZ's drivers.

I tested up to 16x FSAA and didn't notice any artifacts.

FSAA worked well for me when i stayed on ATI and x86.
On the other hand I don't doubt the problem is with intel graphics drivers, but it doesn't help much. I was trying to figure out if some xorg.conf tweak is known to fix this.

Curious, what happens if you raise/lower the texture resolution ?

[NoQ]

Nope, doesn't help
