Created attachment 49020 [details] ENABLE_3D_RENDERING moved to be a normal feature This seems to rectify the problem for ENABLE_3D_RENDERING (moved to be a normal feature, rather than a forced define). However, I'm not sure how to do that for WTF_ENABLE_ACCELERATED_COMPOSITING, which doesn't appear as a "feature". Help would be appreciated.
The patch looks good to me, if we only try to restrict it to ENABLE_3D_RENDERING. Noam, can you change the bug title and ChangeLog accordingly ? I think we should open another bug for ACCELERATED_COMPOSITING as it will likely involve changes to other ports as well, not just for QtWebKit. In general USE(xx) flags are not meant to be turn on/off optionally at build time within a given WebKit port.
Comment on attachment 49020 [details] ENABLE_3D_RENDERING moved to be a normal feature LGTM, r+. I will update the title in the ChangeLogs as well during a manual commit.
