As of version 18.0.0, Firefox regularly overwrites portions of my screen when it is maximized but not active (i.e., Outlook or Word); is there a fix for this?

Posted

Any time I have Firefox maximized but not active (so it's behind another active window/application) on Windows XP Pro SP3, it regularly overwrites major portions of my screen. If I move the mouse, type, scroll up/down, or do other things to change the screen, the active application slowly starts to appear. For example, in Office 2007, when this happens I can continue typing a sentence in Word or Outlook and that line will appears, but the rest of the message area will show Firefox remnants. If I move the mouse along the Office ribbon, it will show up in chunks are the mouse reaches it. This problem has been occurring regularly ever since version 18.0.0 and has persisted in 18.0.1. I prefer not to minimize Firefox so I can conveniently switch via Alt-Tab to/from Firefox and the other application I'm working in, but this issue is making that nearly impossible. FYI, when I'm in Firefox, no other applications pop through onto it, no do any other applications show through otherwise, so I know the issue is being caused by Firefox and/or some weird interaction with the new version and installed plugins, drivers, or other software.

Chosen solution

Could you try disabling graphics hardware acceleration? (I'm having trouble determining from your "More system information" whether it's enabled or disabled.) 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"

If you restart Firefox, is the issue resolved?

Chosen Solution

Could you try disabling graphics hardware acceleration? (I'm having trouble determining from your "More system information" whether it's enabled or disabled.) 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"

If you restart Firefox, is the issue resolved?
