Summary0037853: Switching back to the Lazarus IDE from different program causes rapid blinking of the IDE windows as they are repainted.
DescriptionI don't remember if this was problem in earlier revisions of Lazarus IDE trunk, but it is now starting to get my nerves. Also focus one of the windows - if it is have one before - is lost during the repaint process.

If I disable "Show single button in the TaskBar" option (Options -> Environment -> Window -> "Show single button in the TaskBar") , then this bug vanishes.
Steps To Reproduce0. Start Lazarus IDE.
1. Make sure that "Show single button in the TaskBar" option (Options -> Environment -> Window -> "Show single button in the TaskBar") is checked.
2. Switch between the Lazarus IDE and other program.

What desktop system your Arch Linux has?
I don't see such blinking with my KDE system.
Can you please compare with older versions of Lazarus. Did the behavior change recently?

I use LXDE desktop environment.

I see if I can get older version/go back revisions to check if it normal or not.

EDIT : Tested with release version of Lazarus (2.0.10), the blinking and lost focus of active window is there.

LXDE is mentioned also in related 0021352. It is about TabControl.
