OpenGL sketches very slow to start on Windows 10 - What is the workaround???
I have a new Windows 10 computer and installed Processing 3.3.6. When I run a sketch that uses the P2D or P3D renderer, it takes over a minute for the window to open and the sketch to begin. Switching to older versions doesn't help.
I investigated in Eclipse using the processing-core source code where the problem can be reproduced. I traced the problem to the PSurfaceJOGL class. The call to NewtFactory.setWindowIcons in initIcons and NewtFactory.createDisplay in initDisplay both take a long time.
After some googling I found that other users have experienced similar problem with the JOGL library. Also found this:
https://github.com/processing/processing/issues/4783
So this is a known issue. The library needs to use native dlls to work and that is part of the problem. I looked at some of the previous solutions I couldn't get any of them to work. Disabling anti-virus didn't help.
Can someone explain the proper workaround for this? I have the native DLLs but adding them to the jogl-all.jar's native libraries didn't help, nor did using -Djogamp.gluegen.UseTempJarCache=false or -Djava.library.path. What can I do to get this to work properly?
Answers
(the native libraries are included in processing distribution, in the core/library directory, jarred up into the gluegen and jogl-all files)
I am still experiencing this problem, although I discovered I can fix it by uninstalling my Symantec anti-virus. I'd rather not depend on Windows Defender though. Is there a better solution?
I keep reading about workaround involving messing with the JOGL libraries but can't figure out what I am supposed to do. Can anyone provide specific and clear steps for what to do?
the rule of dumb is never place opensource under windows C:\Program Files :)
