Stetho view inspection crashing apps on Android P DP4

[something15525]

Looks like the Stetho element inspection is crashing on the latest Android P developer preview. Using an emulator with build number sdk_gphone_x86-userdebug 9 PPP4.180612.0074860066 dev-keys, I get this crash when trying to do an inspection of my view elements:

Let me know if there's any other way I can help! Tried this on an older build of Android with no issues.

Looks like this started being enforced in P: https://developer.android.com/reference/android/graphics/Canvas#clipRect(android.graphics.RectF,%20android.graphics.Region.Op)

Looks like a potential solution might be here: https://stackoverflow.com/a/50247323

The offending line: https://github.com/facebook/stetho/blob/v1.5.0/stetho/src/main/java/com/facebook/stetho/inspector/elements/android/ViewHighlightOverlays.java#L141

Any update on this? I can't use stetho because of this issue :(

Please provide a fix. It's 100% reproducible.

Chose TargetSdk 28, attach the inspector and expand the element tree.

@jasta can we wait to close this until a release? seems to make sense
