Is your feature request related to a problem?

Double frame buffers

Describe the solution you'd like

I am looking to enable double framebuffers and avoid tear effects. It seems that the flush functions are not ready yet to handle two buffers.

Am I missing something or the code is not there yet?

Thank you.

Describe alternatives you've considered

I did enable the settings regarding the frame buffer allocations. Got LVGL showing the performance monitor for a while before it resets by the task watchdog,

Hi @barbiani, the P4 BSP is ready to use double buffer.
In menuconfig, try these:

1. (Top) -> Component config -> Board Support Package (ESP32-P4) -> Display -> Set number of frame buffers to 2
2. Avoid tearing effect set to enable

Now, it is a little slow. We are working on PPA acceleration.

HI @barbiani, was it your issue fixed? You can try the latest version of our BSP or LVGL port.

I am also in another issue here

I am using a different lcd controller, so this code was customized by the manufacturer.
