TLDR : what's the outcome on your side with -Dsun.java2d.noddraw=true  -Dsun.java2d.opengl=True ?

I continued to reproduce your issue with "random" changed.

I first tried to compare the list of GraphicsConfiguration with the single one referenced by GLCanvas and was surprised by two things : (1) all configurations in the list are exactly similar (2) all of them even the one held by GLCanvas had hardware acceleration turned off.

I then tried enabling hardware acceleration from Windows settings and activated/desactivated it for javaw.exe. Hardware acceleration was still always off.

(tried updating drivers but they were up to date)

I then tried playing with -Dsun.java2d.opengl=True (or true for no console feedback):

- When -Dsun.java2d.noddraw=false  -Dsun.java2d.opengl=True : single configuration in the list with activated acceleration, GLCanvas has disabled acceleration, GL Version 4.6
- When -Dsun.java2d.noddraw=true  -Dsun.java2d.opengl=True : single configuration in the list with activated acceleration, GLCanvas has disabled acceleration, GL Version 4.6
- When -Dsun.java2d.noddraw=true -Dsun.java2d.opengl=false :  6 configurations in the list with disabled acceleration, GLCanvas has disabled acceleration, GL Version 4.6

So I still can't reproduce your issue, neither activate acceleration for my GLCanvas BUT without understanding why, -Dsun.java2d.noddraw=true  -Dsun.java2d.opengl=True won't lead to a multi-configuration so MAYBE that may have an impact on your side.

Console output in this case with this updated version of the test : JoglContextTestCase.java
