NPE when loading webpages that use large textures when rendering

    Details

    • Subcomponent:
      web

      Description

      I instrumented the runtime and found that WebView requests a very large texture without clipping it to the drawing area. All graphics cards have some limit (usually either 4K or 8K), and will fail to allocate a texture with either a width or height that exceeds that. Note that this is an addressing limitation not a memory limitation, since the texture in question does not take up all that much memory.

      Note that on my graphics card, I also get an NPE on www.yahoo.com (which uses a texture of > 4K but < 8K).

      To reproduce this:

      java WebLauncher http://autos.yahoo.com/
