Tasks window corruption

I am frequently seeing corruption of the task names in the Tasks window – especially when tasks have similar names with spaces in them.

I almost always leave the Tasks window open and notice that when tasks come and go the window regularly shows corruption of the task names (particularly if the Tasks window is partially obscured).

I have used my own tasks (written in Basic) since the days of my first A410 and I do not recall seeing this problem on any real Acorn computers (A410, A4, A5000, RiscPC, etc) or on Virtual Acorn. But noticed it as soon as I got my first Raspberry Pi and I am still seeing it now with a very recent overnight build.

Obviously not a major issue, as forcing a redraw of the Tasks window corrects the text.
