Some draw actions extremely slow on Amiga native chipset

[hth313]

I have so far seen three cases when this happens.

1. The cat eyes no boot media screen is drawn very slow.

2. Horizontal scroll in the 'more' text viewer tool. A file with long lines are truncated, try to use the horizontal scroller and it is terribly slow.

3. Using the C= Installer tool to open a file that does not exist, i.e. Installer foo, which puts up a rectangle with an error over the window, after a while. Once up, click Proceed and watch it go away slowly, pixel line after pixel line.
