It seems on some configurations (Win32 NV Quadro FX 3k 4k / GeForce 8000/9000 ..) calling glBindFramebuffer() fails the 1st time with GL_OUT_OF_MEMORY (checked by glGetError()..). Below I have copied a proposal suggesting to disable the NVidia desktop manager software, which is said to 'eat all vram!'. Another issue could be the infamous NVIDIA 'Threaded optimization' issue. http://jogamp.org/git/?p=jogl.git;a=commit;h=5166d6a6b617ccb15c40fcb8d4eac2800527aa7b Please turn 'Threaded optimization' off, since we use multithreading. Would be helpful if we can verify whether this bug still exists with todays drivers or not. A workaround might be useful as well ? +++ Works: - Windows 7 64-bit Quadro FX 5600 - Vista 64-bit Quadro FX 5600 - XP 32-bit ATI Radeon HD 2600 - Windows 7 64-bit nvidia GE Force GTS 360M. - Windows XP 32-bit Ge Force 8800 GTS driver 190.62 FAILS: - Windows XP 32-bit Quadro FX 3000 (cube is black) - Laptop Windows XP 32-bit Quadro FX Go 1400 (cube is black) - Windows XP 32-bit GeForce FX5200. Driver version is 175.19 a.k.a 126.96.36.19919 (5/16/2008) - Windows XP 32-bit and the Quadro FX 4800 with the latest drivers. - latest drivers the demo hangs and only shows a black screen. - 190.38 driver the demo runs but the texture read from the FB and mapped onto the cube is corrupt. - Windows XP 32-bit, GeForce 8800 GTS latest drivers from NVIDIA. - Windows XP 32 bit, GeForce 8800 GTS, driver version 109.62 +++ http://www.java-gaming.org/index.php/topic,22485.msg186124.html#msg186124 i found what the app disturbed. -the nvidia desktop manager software eats all vram! (after deaktivating this program all works fine again (i use 2 screen ,and got no need of any extra screen manager... must be activated in any way) +++ +++ http://forum.jogamp.org/GL2-context-for-win-build-216-memory-in-build-209-td1908947.html http://forum.jogamp.org/glBindFramebuffer-not-working-td2489325.html

Well, since Windows XP ran out of life (EOL) .. and we didn't experience this bug in an supported environment - closed.
