This issue has been going on for a while now, through several versions since about 59 or so. I'm running Windows 7 Home Premium on a Very fast computer with 8 Gigs of ram.
The issue is that when Firefox is open and I drag another open window in front of it, it leaves white lines and stripes of varying widths, like "ghost trails" from the trailing edges, across the Firefox window below. (see photo) Those lines stay there until I click on the Firefox window, bringing it to the top. Then the window's border and menu bar will repaint, but the window content itself doesn't until I click the top title bar and start to drag the window.
This only happens to Firefox, and not with any other open windows or applications at all. It also doesn't matter what open window is being dragged in front of it, whether is a file explorer window or another program app.
I've read up on other "repainting" issues, but this seems to be different and non of the other solutions seem to have any affect. Not enabling or disabling Hardware Acceleration, or turning Clear Type on or off.
Any ideas would be greatly appreciated.
FYI... I tried adding the picture, but the little image upload box below just has the wheel spinning for the last 20 minutes. So, if the image doesn't show, then it must not have uploaded for some reason. Going to click "Post Question" now. Hope it works.
