There was found, I think, a good way to get away of this "issue" (the temporary addition to an extended style of windows a flag WS_EX_KOMPOSITED *) - but I want to find the reason of it.
Do not judge strictly an amateur in programming. Embarassed

Embarassed

After a series of experiments with MS Spy++ utility I made some conclusions, this "issue" has two causes:
1. Child windows of traditional Windows applications have a flag of style CS_SAVEBITS. Child windows of UPP apps, this style does not have (or have, but not all).

I guess you have got the term "child window" wrong. CS_SAVEBITS is intended for popups.

Quote:

After the forced set of this flag to all windows, "issue" only occurs if UPP application is busy, for example when I opening a package in TheIDE or doing "Rescan Code".

For one thing, there are no child windows in U++... Smile

Smile

(Except DHCtrl descendants, but that is a special case).

My guess is that WS_EX_COMPOSITED only helps accidentally - it changes repainting process of windows and as side-effect, the effect is gone. In the same time, it is not unlikely that this will still depend on actual windows version, graphics driver etc...
