Hi,
using SDL_UpdateWindowRects () with SDL_Rect instances that do not clip
to the bounds of the SDL_Window causes a BadValue error on X11, if
shared memory is enabled:
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 142 (MIT-SHM)
Minor opcode of failed request: 3 (X_ShmPutImage)
Value in failed request: 0x5
Serial number of failed request: 67
Current serial number in output stream: 70
Attached is a test program to recreate the behaviour (please give it a
try to see, if it fails for you, too) along with a simple patch for
SDL_x11framebuffer.c (rev. 6303), which reduces the rect area to the
window bounds.
I am not sure, if XPutImage() is more robust here, so I applied it to
the non-shared memory version, too.
Regards
Marcus
