Description Tony Wang 2009-05-08 08:55:11 UTC 
Please describe the problem:
gtk-DFB backend UI flickers when mouse enter/leave, and mouse press/release events.

Steps to reproduce:
1. compiling gtk+ using DFB backend
2. run gtk-demo
3. press Info(or Source)by turns
4. then move mouse out of the UI(or enter the UI from outside area)


Actual results:
for step 3, you'll find flicker problem
for step 4, you also find flicker problem

Expected results:
there should be no flickers while these mouse events take place

Does this happen every time?
absolutely

Other information:
1. you may find part of the gtk-demo UI flickers
2. my gtk-dfb app encounters the same problems, but my whole UI flickers, what's more, while I move mouse from one button to another button in my app UI, the whole UI flickers too

It looks like you have managed to set your system up with no buffering.
This is a option in directfb off hand I don't know if its in the config
file or not but it can certainly be done via function calls.

So check your config DFBARGS settings etc.

DFB demo programs should also flicker.
You should check this and if true post to the directfb dev list
if you can't find the offending setting.

The directfb backend has been removed form GTK 3
