I get \"Native crash at /system/lib/libwebviewchromium.so\" errors many times for android 4.4+. There was no such problem before 4.4.

This could be caused from a graphic memory bug, so you can try to disable some CSS using any -CSS webkit-transform like " -webkit-transform: rotate(0deg) scaleX(1) scaleY(1); ". (I saw this same bug on iOS if you load too many data in GPU memory).
I'm experiencing a very similar issue with my app on Android 4.4.2.
I found this thread on Chromium support forum that identifies the issue I think is 100% relevant to me, and may be relevant to you.

334992 - WebView on Nexus 10 with stock KitKat 4.4.2 crashes when scrolling up or down
Basically, when attempting to scroll (up-down, or left-right) on long content that has not fully loaded, you can reliably make the webview control crash.
It only happens on some devices (like it happens on Galaxy S5 for me, but not Galaxy Mega), but always seems to affect Android 4.4.2.
Check out that Chromium thread, and I hope that helps.
There's a chromium bug link on this line:

Most probably, the GLES implementation on genymotion is missing OES_EGL_image_external* *http://www.khronos.org/registry/gles/extensions/OES/OES_EGL_image_external.txt
