Firefox 13.0.1 shows distortion in browser during scrolling, why?
I am using Mac Book Air-latest edition; Lion 10.7.4.
While scrolling either up or down - in any window in the Firefox browser, there is a horizontal line or two that runs across the screen only during the scroll process.
This is only in Firefox. Safari is fine when scrolling and so are all document types.

This could be the result of "smooth scrolling." Could you try disabling it?
Firefox > Preferences > Advanced > General
Uncheck the box for "Use smooth scrolling"
Does that help?
I just disabled the smooth scrolling, but no change in the problem. Thanks!
Could you check in Help > Troubleshooting Information, toward the bottom, there is a section entitled Graphics. If the value for "GPU Accelerated Windows" is greater than zero, you might want to try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You usually need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
orange Firefox button or classic Tools menu > Options > Advanced
On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"
Then restart Firefox and test again. Does that fix it?
I have done the changes, but am still experiencing the distortion!
Nothing else comes to mind, but I understand the MacBook Air is somewhat unique among Macs. Maybe edit your original post subject line to mention MacBook Air?
Thank you for your help! I will resubmit tomorrow with your suggestion. D
Try to disable hardware acceleration in Firefox.

Ciao ragazzi, anche io da qualche settimana avevo un problema più o meno simile a questo, e in qualsiasi pagina internet io mi trovavo, che stessi leggendo un documento o stessi guardando un'immagine, mi si creava nel monitor un fastidioso "effetto onda" quando usavo la ruotellina del Mouse per scendere o salire! Per fare un esempio era come cercare di leggere un giornale sotto l'acqua e dava una brutta sensazione di nausea dopo pochi minuti che stavo al PC!!
Adesso grazie a voi e a questa guida ho finalmente risolto!! ^_^ Yeeeee!
Per la precisione io ho seguito questa procedura: FireFox > Strumenti > Opzioni > e nella finestra ho disabilitato la voce [Utilizza lo scorrimento veloce]. Stavo quasi per disinstallare FireFox e passare ad un nuovo Broswer, fortuna che mi hanno fatto leggere prima questo link ^_-
Grazie di nuovo a tutti. Ciaooo.
