--- Comment #6 from Zoltán Böszörményi zboszor@pr.hu --- I don't know if it's a regression or if it's in Mesa at all.
When did Chromium started to use the vertical sync?
49 and 51 didn't print this, but it's true that we used 12.0.x or 11.1.x for them.
On other machines with Intel J1900 CPU (i965) or AMD Kabini (radeonsi) this message is not printed by Chromium.
