Hi yaroslav,
there may still be a problem with memory management or full variables.
I have recorded a longer sequence in automatic mode. After several minutes, I noticed that the screen display was increasingly jerky. The effect became so strong that the app almost froze. If you leave the camera mode, e.g. switch to the Explore tab and then back to the camera, the app runs smoothly again.
In manual mode, the effect is also present, but not as strong. But that may be because I took fewer photos.
