Hi!
Since the latest updates I've got silly glitches in texts. I often encounter it when doing copy and paste.
It happens on both, my PC and laptop (both on radeon drivers). The interesting part is that it doesn't happen for all texts but is always reproducible for certain texts (kinda scary - code injection?). I assume that it is either related to the open source radeon graphics driver or freetype 2.4.11.
You should be able to reproduce this, so please try! This needs to be fixed as fast as possible!
Here's how to reproduce:
1. Copy the code from the Codebox below. Don't worry this is just some code I posted today on the forum and the glitch occured. This also happens for other code but I caught this one "in the act". So if you're affected this will make it glitch
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!-- Replace generic bitmap font names by generic font families.
These font-families will get replaced by other rules and
default to scaled ones. -->
<match target="pattern" name="family">
<test name="family" qual="any">
<string>Helvetica</string>
</test>
<edit mode="assign" name="family">
<string>Arial</string>
<string>Liberation Sans</string>
<string>sans-serif</string>
</edit>
</match>
<match target="pattern" name="family">
<test name="family" qual="any">
<string>Courier</string>
</test>
<edit mode="assign" name="family">
<string>Courier New</string>
<string>Liberation Mono</string>
<string>monospace</string>
</edit>
</match>
<match target="pattern" name="family">
<test name="family" qual="any">
<string>Times</string>
</test>
<edit mode="assign" name="family">
<string>Times New Roman</string>
<string>Liberation Serif</string>
<string>serif</string>
</edit>
</match>
</fontconfig>
2. Now attempt to make a new post by clicking "Post reply" in this forum and paste the code into the text field.
3. Type some random letters.
4. The glitch should occur.
This is of course only one example! However I didn't investigate further in this issue so far.
Here's a picture how it looks on my computers:
My graphic cards: ATI Radeon HD 4770 and ATI Mobility Radeon HD 5650
If you experience the same, please post. Don't forget some graphics hardware info
best regards

EDIT: I think this Thread might actually fit better into the Kernel & Hardware-category. Would be nice if a mod moved it
the correct sub forum. [Moved. Thanks!]
EDIT 2: Might it be connected with this glitch https://bbs.archlinux.org/viewtopic.php?id=156460 ?
EDIT 3: I'm using xfce with xfwm. Now also tried OpenBox but the problem persists, so it's not the window managers fault.

Ok, I found out that it's related to firefox. Maybe it's connected to the current font rendering troubles in firefox 18 https://bugzilla.mozilla.org/show_bug.cgi?id=828206 ?
If someone can reproduce this, please post.
UPDATE:
Yep, firefox 17 isn't affected!
