So to the extent that this issue is related to the GDI object count and really that would be the only explanation, we will develop a solution but allow us a few days or a couple of weeks. We have to try out some different ideas and also discuss this with the developer who worked on what is called the GDI object pool.

We had hoped, that this would create efficiency but really the Windows API is quite inefficient with GDI object management. It is quite ridiculous it is struggling with even just as little as hundreds of objects. One thing that we learn as time goes by, is just how poor in many areas the Windows operating system is. So really the core inefficiency is more at the OS level than anywhere else. Or I guess this problem probably will just get worked around when we add support for OpenGL which we are currently working on. So we may just work on a quick patch in this particular case.


But in general, for the average user, they are not going to notice this kind of problem. The GDI object count should be reasonable.
