Hello,
I'm currently developing a project using Touchgfx on a custom board with a STM32F469II, external RAM/FLASH, SD card and a 1024x600 screen.
I've recently come across an issue when performing any animation (slide screen transition, scrollable container, box/circle progress, ...) where the screen shakes like crazy (see video) and also during a small moment after.
Any movement seem to be able to trigger this issue and the only way I've found to stop it is to disable chrom-art but then the frame rate drops down to about 15 fps when performing those animation.
Does anyone know what's causing this shaking ? And if so, how can I limit it as much as possible ?
Thanks in advance,
Tristan

have you tried triplebuffering / animation storage?

Today I was playing with Debug/Release configurations and suddenly Release one gave me terrible screen jitter and distortion. The main difference was a code optimization (for size) in Release configuration, while Debug has no optimization at all, and Debug is working fine. When I disabled optimization for Release all problems are gone.

Yes this too have very terrible efects, but use without optimizations isnt way.

I think you should share the project files so other people can verify and investigate the issue further 🙂
