Hi,
i am having a very tedious problem with my java application where the context cannot be created because the PixelFormat cannot be set. This happens absolutely random.
Like sometimes i start and close the rendering window 100 times and it works perfectly. Other times it happens on the first atempt.
It is a swing application which uses jawt to connect lwjgl and opengl.
Problem appears with function:
GDI32.SetPixelFormat(hDC, pixelFormat, pfd);
The last error is 2000 -> The pixel format is invalid.
I discovered that everytime it succedes to set the pixel format is when the hDC has no pixel format set before. And when it fails the hDC has a pixel format set with index 186 and description 220.
I dont know why suddenly that window has a pixel format set.
I discovered that passing -Dsun.java2d.opengl=false as vm argument to the java application solves this particular problem, but then my swing GUI has some weird scaling problems, which is no solution for me.
Sadly i cannot reproduce it with a simple test project :(.
So here goes my cry for help:
How can it happen that a drawing surface has already a PixelFormat set, which impedes me from setting it one?
And most importantly how can i solve it?
Background info:
Currently using LWGL 3.1.6, tried using the 3.2.3 with same result
AWT connection based on Kai Burjack's implementation -> https://github.com/httpdigest/lwjgl3-awt/
Using Java JDK 1.8
GraphicCard: GeForce RTX2070 with latest driver 436.30
Thx a lot in advance.
