However already built chromium works fine if you remove gtk2. Reproducible: Always
Created attachment 415688 [details] build.log
Confirmed. It's not as simple though - I ran into issues with GYP build - it may be saner to retry this with GN.
Also true for 48.0.2552.0
Also true for 53.0.2785.34
We are aware it is broken, no need to tell us again.
Uploaded https://codereview.chromium.org/2342163002 upstream.
The ebuild DEPENDs on both gtk2 and gtk3 now.
