touchGFX function startMoveAnimation is leaving dots in the path. why ?

[Eblec.1]

it is not happening on simulator. only on my real target !

[Eblec.1]

is there any initialization that is running on simulator and NOT on my real target ?

[Eblec.1]

today I tried this on evaluation board stm32l496g-disco and it works ok without dots left behind.

the disco has a screen 240*240. my screen is 320*240. can it be the reason to the dots left behind ?

Hello @Eblec.1​ ,

What do you mean with leaving dots in the path ? Could you provide more details about your issue and maybe also screenshots ?

hello, Yoann.

I added an image that shows the dots left by the animation of moving the box through the screen.

thanks.

Hello Eblec,

Try use <box>.invalidate() for the background box and execute it in each tick event

[Eblec.1]

thanks. I'll try this. but isn't it a workaround to fix an animation problem ?

Hello Eblec.1,

You said that on the stm32l496g-disco it works fine but on which board it's not working fine ?

hello, Oskt.

it works fine on the disco, which has 240*240 screen.

it leaves dots on my custom board with a screen 320*240.

I declare in touchGFX the 320*240 , and only the animation leaves dots.

thanks.

Hello Eblec.1,

Ok, and what did you put for dimensions of your application on TouchGFX Designer ? 240*240 or 320*240 ?

Also did you modify the dimension of your display with STM32CubeIDE ?
