Comment 20 for bug 54285

AthlonXP 2200, 768MiB, all 32 bit, no noticeable interface lag in firefox or elsewhere. I get this bug across all installs, all versions: I've just tried it on an edgy install as well.

For the record, I initially said you needed focus-follows-mouse, actually that isn't true as firefox will show title tips from an unfocused window.

All I have to do is hold the cursor over the image long enough to start the tip delay timer (the one that stops the tip showing immediately, which on my machines means just running the cursor straight over the image and out is enough) and then move away before the tip actually displays. The tip will then draw over whatever is on the screen by the cursor.

To make the screenshot I literally just moved the mouse from the left of the screen to the middle, passing over the titled image.
