👋 Hi @jrodbx @geoff-powell, it seems like this layoutlib update introduces unexpected changes regarding colors.

For instance:

• https://github.com/cashapp/paparazzi/pull/2185/files#diff-442e6f3421d8b58171f57529c62fc910740ae6c84a1ba8321d9bb3ef34095cf7
  The background color changed from #FFFFFF to #FAFAFA
• https://github.com/SimonMarquis/Android-Playground/pull/440/files in my own project has similar issues with background slightly changing color (this from #faf8ff to #faf8fe)

Is it directly related to this update? Is it known?

[geoff-powell]

Yes, I assume that is due to the layoutlib updates. I can try and look in the source for any recent changes
