I can reproduce this locally with an Android build running WR-enabled crashtests on my local Pixel 2:

# debug arm android build in mozconfig
./mach build
./mach package
# plug in device for next two steps
./mach gradle installWithGeckoBinariesDebugAndroidTest
./mach crashtest --enable-webrender dom/base/crashtests/ # select no when prompted to re-install geckoview test app

Hi tnikkel, in bug 1864255 you moved this test, do you think there's still a crash we need to track?

[Timothy Nikkel (:tnikkel)]

I'm not sure. I pushed to try with it enabled to see what happens.

The test is quite intense, it opens so many windows that I was unable to find a way to close them all that actually worked in practice (hence the reason I had to move it). The test is also disabled in other configurations that aren't as fast (asan, tsan), so we might just have to accept that android can't run this test.

Looks like it runs fine on try now. I did TV jobs and many retriggers. I'll post a patch to enable it on android.
