Austin told me the anti-aliasing is not broken

I also have this issue when using 2xMSAA with a RX6800XT card.

On Linux, the scan line issue is not present at 2 x MSAA. 6900XT.

Not sure I've encountered it on a few short XP12 tests on Win 11 either.

There was a big dicsussion on the org forum. If I remember correctly, it was only related to AMD cards.

I'm not doubting it exists, as Bog posted a screenshot of it.  What I have a problem with is his CLAIM that it's a known issue.  I have 3 Mac products.  Intel MacBook Pro (with AMD GPU inside), 2020 Intel iMac (with AMD GPU) and an M1 Max MacBook Pro.  I also have an external AMD GPU for the Intel MacBook Pro.  I haven't seen this "known" issue he's claiming, at any time.  Therefore, I posted that it must be an isolated issue that only occurs under specific circumstances.

What does mean slack group? Do you have another word for it? I´m not an english nativ speaker.

Slack is chat software that anyone can use.  Laminar have a Slack discussion group that testers and developers have been a part of for about 18 months (invitation only), and were testing X-Plane versions since it was released internally.  It is still being used for every X-Plane 12 update and feedback.  As I said previously, I haven't seen any mention in the Laminar Slack group of this "known" problem that Bog mentions.  There's talk about anti aliasing and MSAA in general, but that's it.

I remember reading that topic, the bug occurred only in 2xMSAA antialiasing mode, and mainly involved ATI RX6600xt, RX6800xt, RX6900xt series cards.

Yes the issue has been discussed and I even remember someone from Laminar acknowledged they're aware of it.
