I have this cursor problem with Chrome. This is the normal situation: The mouse pointer is in the shape of the text cursor "I" and it's inverted. But sometimes it's just white. Then it's invisible on a white background and I have to move the mouse around and try to find the cursor over the text (to see white pixels of the cursor over the text). And the situation with invisible (white) text cursor/pointer: Here the cursor is over "mp" (between them) part of the text. There are some white pixels of the pointer over the text symbols "mp".
