Since I've deleted the line "panel_as_texture=0" in FS9.CFG (that gives the same effect as panel_as_texture=1) the outside view bleeds trough at some places along the left, right and upper edges of some 2D panels.Looks like a gap of 1 pixel around the panel image at some places.This happens if the above line in FS9.CFG is not present or =1, and with antialiasing switched to on in the driver (no matter what value).I have a Radeon 9800 Pro and Catalyst 4.12 drivers.I already did all I can to get rid of this, but since it seems to be a very generic problem (i.e. independent of FS9.cfg or the drivers, I already let FS9 create new FS9.cfg's and used Omega drivers as well as older Catalyst versions), I wonder if no one else discovered this.Seems to occur when panel bitmaps have an original size bigger than my screen resolution of 1024x768, 'cause it happens e.g. with PMDG 737NG and FSDzign's Lockheed 049, but not with the default Cessna 172.As soon as panel_as_texture=0 again, the effect is gone, but I'm loosing more than 6 FPS.Another method would be setting AA to "application controlled", very bad to my eyes and thus not a viable way.Any ideas?Andreas

I'd love to know if there's a solution for this as well...

If you are not afraid to edit your panel.cfg file for the aircraft, here is how to fix it... go to the "Default view" section, likely at the end, and make the following changesX=4 //was 0Y=0SIZE_X=8182 // was 8191Adjust the Size_X number to be 9 less than the original.Since this gets scaled back to 1280 screen resolution, you still want there to be one pixel difference...

I thought of doing that, too. I already did some experiments with the definition of the panel windows (e.g. replacing size_mm with pixel_size and so on) just to discover more strange effects like gauges not sdisplayed at all etc.The whole thing seems to be more complicated as I initially thought. It has something to do with the way the panel is overlaid on the background outside view. When AA is on, I have the impression that there are belt-shaped areas (i.e. broad horizontal belts of n pixels height) where the panel is only w-2 pixels wide and positioned 1 pixel to the right off the 0 mark.Popup windows cannot pass these boundaries as well. Looks like the background is 2 pixels broader at these belts, thus shining through at the edges.And there occasionally lines at the upper edge wher the background "bleeds through" as well.In fact, it's not a simple bleed-through effect, the panel bitmap is rather somehow 1 pixel smaller than the outside view behind it at some areas on either edge.Changing panel.cfg parameters such as render_3d_window affect the behaviour somehow.A riddle for me, indeed. Somehow AA disturbs the screen edges. And, the strange thing is that even when I make the main panel invisible and the screen shows full outside view and the screen edges are all clean and straight, there's an almost undetectable color difference where the belts are when the main panel is switched back on.I'm curious about that, and I wonder why I'm alone with this problem here.Seems that I either need to switch and try another graphics adapter (don't have the money for that currently, and I don't know if that would be the cure), or put back panel_as_texture=0 with the FPS loss, or switch AA completely off (don't like that, better get the line back in FS9.cfg).Andreas

Addition/Correction:The workaround I'm going to use is:[Default View]X=4Y=4size_x=8179size_y=3562for the Lockheed 049 panel.I can always increase/decrease these values, guess especially size_y would depend on the panel used.Thank you so far, I'd interested in an explanation of this effect, though...Andreas

Happy it is working for you!Size_y indeed depends on how far down you want the scenery to display...I would not worry too much about why it is happening, I have a Nvidia card and have the same issue, so I doubt it is your card.
