[Bug 1299915] [NEW] Symbols are occasionally distorted in different programs

 

Public bug reported:

Sometimes, symbols in a text are distorted in different programs like
Firefox or LibreOffice Writer. The distorted symbols look like random
distributions of pixels. An example can be seen in the attached figure
showing the distortion in Firefox.

P.S. Actually, I am not absolutely sure that this is compiz which is
affected by this bug. If it's not, I offer my apology and ask those who
know the right project to correct the report. Thank you.
