Hi. all.

I'm using VISION SDK 3.4.

My goal is to make a chain like below.

dec(M4)->display.

weston(A15)->display.

I found an usecase in vision sdk for each. ( disp_dist_src_display / null_src_decode_display)

I tested both, and it works well.

So, I merged 2 usecase to one usecase using alpha blending.

But, displayed image is broken seriouly.

Below is my test sequence.

1. run apps.out. select my usecase.

2. run weston-simple-damage

If I run weston-simple-damage with small size, display is not broken.

But, with large size (weston-simple-damage --width=1280 --height=720), display is broken.

I turned off alphablending. but the result was same.

How can I fix it?

What is your display resolution?
Can you share a screenshot when you have not launched any wayland client, but only weston is running, and one when you are running weston-simple-damage with a smaller resolution?
Can you also try other wayland cients like weston-simple-shm and share the screenshot?
Regards,
Subhajit

Resolution is 1920x1080.

1. Display with weston only.

2. with small weston-simple-damage

3. weston-simple-shm

With small size client, there's no problem.

I also tested with simple qt program. But the result was same.(Small size is ok, big size made display broken.)

Sorry for the delayed response. I assume that the image of the ship is from the video (decoded in M4). Can you tell me where is weston wallpaper in the first image where there is no other client?

Did you make sure that the zorder of the video pipe and weston pipe are different?
