[arch-general] Garbled Text in KDE 4.2

Hi everyone, I have recently upgraded to KDE 4.2 (vanilla, not kdemod) and have noticed an odd glitch. Every once in a while, with no pattern I can discern, the font in the title bar of a window will have garbled text in it [1]. When I took that screenshot and was about to save it, I noticed that the file chooser dialogue also had the glitch, as did the text in the dialogue [2]. The fonts are Sans Serif 10 bold. Does anyone know why this would happen? -- Leonid [1] http://img149.imageshack.us/img149/998/garbledzr9.png [2] http://img230.imageshack.us/img230/2577/garbled2sw8.png
