* Changing the font size in the application (terminal, Firefox) also temporarily fixes the issue
* Some images in Firefox also become garbled, but recover after a forced reload.
I can confirm that the issue still happens with the mainline kernel (linux-

Same problem here, also using an intel video card, in this case a gma4500. Unlike you I use openbox with xcompmgr. It does seem to be video driver or Xorg related.
