How can fonts cause OpenGL out of memory error?

Question

I have a problem with my AppWidget. Some users on Galaxy Nexus and Nexus S who have Android 4.0 are reporting broken fonts in stock launcher.

I had the phone connected to ADB to see the logs and I found there these errors multiple times:

OpenGLRenderer is out of memory!

Is there a way to optimize AppWidget to be less memory demanding for OpenGL renderer?

Is it sufficient to reduce the levels of the view tree?

The Android engineers have found that very large font sizes can cause low-memory conditions in the font cache in Ice Cream Sandwich 4.0. They are working on ways to more effectively cache fonts that require a lot of memory. No workaround was proposed at this time.

To be less demanding, reduce font size.

Note that this is an issue only on GPUs that use a deferred rendering architecture. For instance, a phone using a Tegra2 or Tegra3 GPU will NOT have this problem. – Romain Guy Feb 23 '12 at 18:18
