When using 8mplus to play qtdemo, the screen occasionally flickers

[Eddy1]

Hi：

Recently, while testing qtdemo on 8mplus, I noticed that the screen occasionally flickers when running the qtdemo provided by NXP BSP. I have attached a video for reference. Can you please help me identify the cause?

which board are you using? we tried on the 8mp evk and we don't see this problem.

Hi：

Thank you for your reply!

We are using a customized board based on the 8mpevk development board. Additionally, BSP 5.10.72 is slightly better, but the default use of NXP’s official 5.10.9 wic file results in a higher frequency of screen flickering

Hello,

Which display/screen are you using? what is the different between your own board and the evk? Have you modify the dts file to fit your own board?

Hi:

Thank you for your reply. I have updated the Weston version (V9.0.0) and Wayland-protocols (V1.22) on BSP 5.10.9, and after testing, the flickering issue is no longer present.
