Reassigning to Mesa. From your bug description you have pointed out that fglrx failed to build so you're not using it. The real issue then is that the Mesa radeon driver is not performing.

My video card is AMD HD7950, and I use an MiniDP-to-DP line to connect it with an Acer XB240H display. With fglrx or fglrx-updates installed, everything renders extremely slow, even raw terminal renders like 100 lines per second. Workarounds failed: * AMD official driver failed to build due to bug #1502978. * The open source driver can only provide 1024x768 resolution.
