Hi,

Just this question for people who can confirm this:

- A WPF normal window is rendered by GPU acceleration
- A WPF window with AllowTransparency="True" is rendered by CPU
The question is here cause I saw the performance are very bad when moving or
resizing (by event + code)

It true, the next question is why WPF doesn't use GPU for transparent window
?

Thx
