App crashes when WebView opens over SVG with ColorFilter on MediaTek Android 10 devices

Summary

Flutter app crashes with SIGSEGV in libGLESv2_mtk.so when opening a WebView modal over an SVG that has a ColorFilter applied. This issue is specific to MediaTek devices running Android 10.

Steps to Reproduce

  1. Display an SVG using SvgPicture.string() with a ColorFilter applied
  2. Open a WebView in a modal/overlay on top of the SVG
  3. App crashes immediately on first launch after installation
  4. On subsequent launches, WebView may work initially but crashes after several open/close cycles

Note: The crash only occurs when running the app in release mode.

Expected Behavior

WebView should open normally without causing the app to crash, regardless of underlying SVG with ColorFilter.

Actual Behavior

App crashes with native SIGSEGV error in MediaTek's OpenGL ES library during EGL context operations.
