Firefox 7 hardware acceleration I have a Nvidia GeForce GT 230 card on a HP computer and after updating to FF 7 blue diagonal lines appeared on screen at start of FF 7 . This has never happened before . I unchecked hardware acceleration when available and it is not doing it now . Anybody else experiencing this problem with FF 7 ?

GPU Accelerated Windows1/1 Direct3D 10 shows when doing about:support so the acceleration is working but I don't like that blue line at start up so I unchecked hardware acceleration.

FF 7 - The only thing that solved this for me was to disable Status-4-Evar.

Same "problem" here. Said lines appear only for a fraction of a second on startup, and disappear afterwards. Started happening right after upgrading to Firefox 7. They look pretty nice, so I thought it was intentional at first :)

Info: I have hardware acceleration disabled (since I don't like blurry fonts). But, like the user who posted above me, I am using "Status-4-Evar" plugin.

Edit: it also happens when I open a new window.

Hi derpyherp,

If you disable "Status-4-Evar" plugin does it cure it?

Just tried, yes it does. I guess we need to let the devs of that plugin know or something.
