Facing some weird issues whiling using X

Hey,

We're facing various problems since we moved to RH6.1 x64 OS.

1. Font – Even though we're using exactly the same font on both servers, yet, it looks terrible on the new server. see image link:

2. Screen get splotch - whenever dragging a window, any window, it gets all blurred and messy. the only way to fix it would be to close and window and to reopen it.

3. Copy and Paste doesn't work all times - sometimes, it is needed to copy few times until it actually copies. same for paste.

4. Keyboard is too sensitive – this cause to print multiple characters.

5. Adds commas when entering '<'

I know, these issues sound pretty unusual but it is just painful to work like this.

Your suggestions would be much appreciated.

Thanks,
Nir.
