When I first start konsole, I very briefly (less than 0.5 seconds) see:

- the menu, window decorations etc. are all normal.
- instead of a grey background where the console text goes, I see a white background.
- this white box has a transparent triangle cut out of it in the top left corner e.g.

|----------|
|\         |
| \        |
|--\       |
|          |
|          |
|----------|

The white background then goes away and becomes the colour it is meant to be. Starting new tabs and changing tabs does not cause this behaviour.

I've tried to get a screenshot but cannot. I can't time it right using ksnapshot.
