Hi Joel,
Bug 4354093 is filed for the texture problem.
We should check the maximum texture width/height support
by the underlying Hardware before creating texture
surface. If input texture size is greater than
hardware can support, the surface size is
created with maximum widht/height support and
the rest of input texture are ignored, with warning
message print out in debug mode (-Dj3d.debug=true).
Note that Texture manager is enabled in current
release if device is hardware accelerated.
if (hardwareSupport) {
ddsd.ddsCaps.dwCaps2 = DDSCAPS2_TEXTUREMANAGE;
}
For the second problem in line clipping,
we believe it is a driver bug.
Thanks for your bug report.
