Hi Sven, Would it be possible to have this bug looked at soon? If you need more information please let me know. Thanks, Owen. the bug is not reproducible for me, the lines are perfectly aligned with the triangle. my test environment: jogl build 350 linux / Nvidia GTX 295 / 260.19.36 looks like a driver bug to me. Can you provide your test setup? I just tried this again with a current build (b350) and the problem is no longer there. I tested again with b266 just to make sure and that build fails. I'll work backwards and figure out which build fixed the problem, then I guess we can close the bug. Windows XP, Nvidia 8400GS, driver 266.58 This was fixed in b283, I'm changing this to resolved. |
Created attachment 207 [details] Application for reproducing the bug We are seeing a bug in JOGL where lines are flipped (but triangles are not) when both these settings are enabled: 1. gl.glShadeModel(GL2.GL_FLAT); 2. caps.setSampleBuffers(true); This occurs on Windows 32-bit and 64-bit, have not tested on Linux or Mac.
