Here is an example of what I mean, the tooltip doesn't show most of the requested text ("example" in this case).

enter image description here

There is more information about my code in my previous question: show contour area as tooltip.

However, I made this post to address the display issue with the tooltip which is likely a broad problem.

Here is the code from the symptomatic screenshot I showed. 

w = 4;
plot = ContourPlot[
    Sqrt[(x - 2)^2 + (y - 2)^2 - 5], {x, -15, 15}, {y, -15, 15}, 
    PlotPoints -> 30, MaxRecursion -> 4, Contours -> {w}, 
    ContourStyle -> Blue, ImageSize -> 250] /. _Polygon -> 
    Sequence[] /. Tooltip[x_, y_] :> Tooltip[x, "example"]

Which can be simplified to just 

ContourPlot[
   Sqrt[(x - 2)^2 + (y - 2)^2 - 5], {x, -15, 15}, {y, -15, 15}, 
   Contours -> {4}] /. _Polygon -> Sequence[] /. 
 Tooltip[x_, y_] :> Tooltip[x, "example"]

and still have the same issue with the tooltip not showing.

I have tried adding a Pane wrapper around "example" within the argument of the last Tooltip, but this hasn't helped.

    $\begingroup$ This example works well on Win7 V9.0.1.0 but I've faced this issue. And it was not stable, sometimes it occures, sometimes not. $\endgroup$

  • $\begingroup$ I cannot reproduce this behavior with the code in the question both in Mathematica 8.0.4 and 9.0.1 under Windows XP SP3. But I faced similar problems when used non-standard fonts for Text inside Graphics. $\endgroup$

    $\begingroup$ In order to reproduce this issue could you provide your PC's specs: Mma version, OS version, service pack level, video card and etc. I cannot reproduce the cut off tooltip with this example either. $\endgroup$

It's a bug. Wolfram is aware of it but has not chosen to fix it.

Sometimes I restart Mathematica to deal with it. If I am running something, for example, in a Manipulate function, I clear the local variables every time it is run. This helps most of the time.
