Not sure if anyone's encountered rapid flashing of the Lazarus windows
elsewhere, but it could be important to resolve due to the hidden
dangers of epileptic seizures.

I hope this is an appropriate way to shine light on this matter I have
at hand. I need to show a bug that has been bugging me lately when
using the very minimal and lightweight window manager called Window
Maker (WMLive ver. 0.96.0-0), along with Lazarus 3.99, from the main
trunk build.

The video accompanying this topic speaks more than a thousand words
could ever express, so please, if you could watch the different
scenarios in the video where this bug occurs, it might help shed light
on its specific nature. For the sake of completeness in reporting
this, what happens is that the Lazarus windows jitter as they are
being resized and refreshed, eventually settling down and recovering
from the jittering. The most severe and frequent phenomenon occurs
when the windows are hidden or minimized; then upon restoration, they
tend to cycle through them rapidly. Depending on my luck that day,
they eventually emerge from that frenzied state, allowing work to
continue.

You could either watch it on my page from an embedded player[1] (under
the "Video Directory") or on YouTube[2], if you prefer it that way.
Thank you for your help in this matter.
