Dear all,
since rev 6494 I am noticing some strange difference in the
SDL_RenderSetViewport() behaviour for OpenGL. Given that a SDL_Window is
hidden, setting a viewport with {0, 0, 0, 0} was a valid operation until
that revision.
Since rev. 6494, the renderer->UpdateViewport() call in
SDL_RenderSetViewport() returns -1 without applying a proper error
message.
Find attached a simple program, which recreates that issue and exits
with the following output for me:
(marcus at medusa)> ./viewport_test
0,0,0,0 viewport setting failed
SDL not built with haptic (force feedback) support
Is this the intended behaviour?
Cheers
Marcus
