Description
Using the TextLayout.fx test case for RT-5100, I get ~30fps - *if* the mouse cursor stays outside the top-level window.  As soon as I put cursor inside the window, things slow to a crawl: 2-3fps.  Curious.
Comments
Run the test from RT-5100 using promoted b35 of soma and I get fps output as follows (even if I move the mouse inside the window).: pt fps: 62.00787425041199 pt fps: 63.97637724876404 pt fps: 64.03940916061401 pt fps: 63.97637724876404 pt fps: 63.05418908596039 pt fps: 63.97637724876404 pt fps: 63.97637724876404 pt fps: 64.03940916061401 pt fps: 62.99212574958801 pt fps: 63.97637724876404 pt fps: 64.03940916061401 pt fps: 63.97637724876404 pt fps: 63.05418908596039 pt fps: 63.97637724876404 pt fps: 63.97637724876404 pt fps: 64.03940916061401 pt fps: 62.00787425041199 pt fps: 63.97637724876404 pt fps: 64.03940916061401 pt fps: 63.97637724876404 pt fps: 62.068965286016464 pt fps: 63.97637724876404 pt fps: 63.97637724876404 pt fps: 64.03940916061401 pt fps: 62.99212574958801 pt fps: 56.35147914290428

Though RT-5280 was backed out, other changes have prevented this bug from re-manifesting.

Indeed - this problem has disappeared along with the fix for RT-5280.
21-08-2009
This may be caused by RT-5280 so it should be retested now that 5280 is fixed.

Could this be related to RT-3781?

The same slowdown happens with GUIMark.
