[Bug 1174678] [NEW] Full screen zoom fails in Mousepad and Leafpad text editors

 

You have been subscribed to a public bug:

I'm not sure if this is a Unity issue or an editor issue, but the same
problem on 2 different editors would suggest the former. Open either of
these editors. Double-click on the title bar to zoom. (Once you do this,
you may never again be able to shrink the window again, beyond a small
fractional amount, because you will never again be able to reach the
bottom border with the "up-and-down resize arrow"; you would need to
reinstall the OS!)

Zoom works fine. Now close the editor.

Launch it again. This time, it tries to come up zoomed, which makes
sense because that was its most recent state. But the last line of text
at the bottom of the screen shows through. (In other words, it would be
a full-screen zoom, but the last line is still the desktop background.)
So you need to double-click on the title bar twice, once to shrink and
another time to zoom again. The second time, it actually zooms
correctly. When you open another file or repeat the experiment, you need
to quadruple-click all over again.

In addition to being very awkward, this is actually quite confusing,
because if you have zoomed and unzoomed editor windows open, the last
line of text from document A shows up at the bottom of document B.

This problem did not happen on i386 12.04 several months ago. Sorry, I
no longer have the specific details. Anyway, it happens now on AMD64
12.04. Reinstalling the OS fixed it for a few sessions. Then it happened
again. Perhaps zooming triggers it.

I have some sense that this bug relates to the fact that Unity has its
own title bar at the top, so somehow the editor is getting the wrong
idea about how big "full-screen" really is.

The reinstall-the-OS-to-resize issue is perhaps another bug, but I'm not
going to open another report at the moment because I suspect that it's
due to the same root cause.
