- compiz crashed with SIGSEGV in
unity::ui::EdgeBarrierController::Impl::OnPointerBarrierEvent()
(LP: #1020075)
- Much slower OpenGL frame rates with unityshell loaded, than plain compiz
(LP: #988079)
- Compiz won't start if "unredirect fullscreen windows" is enabled
(LP: #980663)
- [regression] Unity launcher on-screen corruption on resume from suspend

Bug description:
[Test Case]
Performance issue - just checking if performance in OpenGL applications with
Unity loaded are normal.
[Regression Potential]
Visual regressions, shell drawing problems. Part of a big change, many
regression potentials.
Original description:
The main problem is that OpenGL apps run slower with unityshell
compared to plain compiz (Gnome Classic).
In extreme cases, running glmark2 under Unity only achieves 0-3 FPS.
Yet on the same machine reports frame rates of several hundred FPS in
Gnome Classic. See comments #28-#30.
In other cases, game performance is OK but still visibly worse under
Unity. ioquake3 drops in frame rate by around 20% in Unity compared to
plain Compiz in Gnome Classic (see duplicate bug 1005074).
ORIGINAL DESCRIPTION:
On my Z600, with a fresh Precise installation, after installing the NVIDIA
driver 295.40 (same version as in gPrecise), glxgears runs extremely slowly
full-screen. When running on Precise, Chrome's GPU accelerated rendering path
produces correct results, albeit extremely slowly.
