Text disappears in Firefox/Thunderbird

Some thoughts:
1) Did you install
2) Does "fc-cache -v" followed by "fc-list" list all the fonts properly?
3) Does disabling acceleration in the X server make any difference?

1) Yes.

2) Seems to. I have the MS core fonts installed because I'm most
comfortable with them for web use. So while non-MS fonts have entries
like this:

Nimbus Mono L:style=Bold

MS fonts are polluted with style details that don't display properly:

Arial:style=Italic,Cursiva,*va,kursiv, »¬³¹±,Kursivoitu,Italique,D,Corsivo,Cursief,Kursyw a,I¡lico,¸²,°talik,P¡evno,ªng,Etzana

That was copied from rxvt-unicode. xterm yields garbage too, just in
ASCII instead of unicode.

My current Firefox preferences indicate that I want to use the MS fonts.
Changing the font settings to all use Nimbus Mono L, I experience the
same result. So the fc-list listing is buggy, but not the source of my
problem.

3) I don't have DRI enabled. Is there some other setting I should check for?


Thanks for your help thus far

Using the above option fixed the problem, yet made scrolling unbearably
slow. So unless there is some fix for that, I guess I'm stuck with the
text problem.

I'm using the radeon driver, for what it's worth.

My Xorg log identifies my chip as follows:

(--) RADEN(0): Chipset: "ATI Radeon 9800SE AH (AGP)" (ChipID = 0x4148)

I don't suppose a fix is currently available, but it's nice to pinpoint
my problem, to some degree. Thanks a lot for your help.

Hmm, I'd check if the radeon driver enables XRender acceleration by
default. There's an option to control it, you may want to turn it off.

have fun
