Xorg videodriver problem with fonts

Hello,

I have a strange problem with xorg video driver:

When in my xorg.conf option"NoAccel" is set to"true",  then everything is displayed correctly, but it's slow.

When I comment this line and restart X, everything is faster, but, for example, openbox window titles are not displayed correctly. This issue only affects fonts.

Inside window everything looks good. See attached screenshot:

There is window of xterm and fbpanel.

I use custom board, based on c6a186x; file system, u-boot and kernel from EZSDK 5_05_02_00. Driver in xorg.conf is set to "pvr".

Can someone tell the reasons of this behavior or how to solve the problem?

Thanks.
