%%%--- Operating System, Graphics card ---
Ubuntu 64, 2*nvidia gtx 560 ti oc 2gb, 8gb ram

- Blender version with error, and version that worked ---

Current svn and official release!

- Short description of error ---

Circle select and box select is selecting wrong vertices apart from the chosen ones :)

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Open the blend file and hit C to circle select
Select via left mouse button some vertices on the facing side and watch the left side..
Some other vertices are selected

Greetings, Thomas

%%%Thomas, please check whether disabling multisamples helping you. Also make sure you do not have FSAA enabled in your video driver settings.%%%

%%%Hi Sergey,
disabling mulitisamples helps! But it should get fixed nevertheless or disabled, don't you think? %%%

%%%Thomas, that's annoying but that's a limitation of drivers/cards. Some of them does not support disabling multisables once they were enabled and in this case selection will go wrong.%%%

%%%And today a user in IRC confirms it works fine for his Linux box with gtx 580.. it drives us nuts, there's no clue yet why, as if every driver/card version is doing it different.

Basically the error is that we should (from blender code) be able to turn multisample on and off. That's a standard OpenGL function. We're on it, but it might result in just disabling the feature.%%%

%%%A question: why not employ offscreen non-multisampled FBO for auxillary drawing (i.e. for picking)? AFAIK, driver overrides and PixelFormat/GLXFBConfig settings have no effect on FBOs/Renderbuffers.%%%

%%%This should be fixed now in svn, the latest builds from http://builder.blender.org/ should have the fix.%%%
