When webkit-gtk is compiled with O2 flags, css appears to be broken on many sites with epiphany 3.14.2 Forcing -O1 fixes the errors. Reproducible: Always Steps to Reproduce: 1. Compile webkit-gtk:4 with CFLAGS="-O2" CXXFLAGS="-O2" 2. (optional) compile epiphany with any CFLAGS 3. visit any github repository and click on the "commits" button Actual Results: The commit list is displayed with text only and bad layout. Expected Results: The page is displayed as with other browsers In Source/cmake there are commands that alter the CMAKE_C_FLAGS_RELEASE variable, adding -fno-omit-frame-pointer and -fno-tree-dce. Is the ebuild overriding this ? I have not tested CFLAGS combinations as build takes more than one hour...

Adding -fno-omit-frame-pointer and -fno-tree-dce didn't fix the problem. Adding -fno-strict-aliasing worked for me on 2.8.1 off the gnome overlay.
I could not believe this but after insulting webkit so much and rebuilding with -O1 to see that everything works properly... I'll try to confirm these CFLAGS are the source of the problem.
Fixed in overlay. Thanks for reporting.
I applied a patch for this in the Gnome overlay. It does not unbreak all websites but at least github and youtube works a lot better. However wiki.gentoo.org is still broken in epiphany. Could you confirm ?
It's strange, I don't have any issue with wiki.gentoo.org either before you filtering strict-aliasing or after that :/
Also try with 2.8.5 from the tree
I have tried 2.8.5 from tree and I don't have the original issue. The problem on gentoo wiki is caused by non accepted certificates, unrelated bug in my opinion.
Closing then, thanks for the heads up.
