Start Up Screen shows desktop before showing default blue screen

[Captain]

Yesterday I installed a few programs on my pc, and now I have noticed a
changed behaviour; prior to the default blue "Loading your personal
settings' screen, the background colour (in my case it is grey) for the
desktop appears for about half a second, it never happened before. I even
uninstalled the programs but to no avail. Could someone please guide me
appropriately.

Why do you think this is a problem - i.e. what trouble is it causing
you? All sorts of things are going on about then, and small timing
differences can cause variations in what you actually see.
