| Summary | 0015791: EGLRenderWindow creates new context when the window is resized | ||||||||
| Description | EGLRenderWindow creates new context when the window is resized. A new context is expensive since mappers have to create create textures etc. Can you check if there's some way to avoid that? Can we create a bigger context by default? | ||||||||

It turns out that I don't recreate a new context when I resize an EGL window. I only recreate a new (offscreen) window. It does not seem to be a way to resize an already created offscreen window. You always create a new offscreen window and specify the size at creation time. See: https://www.khronos.org/registry/egl/sdk/docs/man/ [^] eglCreatePbufferSurface |

Can you see if we can avoid having vtkOpenGLGPUVolumeRayCastMapper::vtkInternal::LoadVolume() getting called when volume rendering and resizing the render window? |
