Caret movement in IDEA X very slow

I'm using a the idea/100.46 build and have to say that the editor feels very
sluggish when moving the caret in a small Java file (< 200 lines).

What can I do to improve the responsiveness?

I hope, I've captured the CPU data correctly.

Hi Tom,

CPU snapshot is ok, thanks. It shows that the problem is inside sun drawing primitives:

I googled that and it seems that there is a problem with jdk 6 update 22 and Substance LAF.

Please do the following:

  1. Provide information about your environment (OS, java version, LAF, IJ Editor font setup);
  2. Try to use another LAF;
  3. Try to start IJ with the following setting '-Dsun.java2d.d3d=false';

Do you know which specific features are unavailalbe in such a scenario? The only thing I can think of is native method profiling..
