Vertical flickering occurs during video playback

[moonlight-aska]

Describe the bug
When reTerminal is used in a horizontal style and a fast-moving video is played by a video player, a line of image misalignment in the vertical direction is observed in the view.

To Reproduce
Steps to reproduce the behavior:

1. Use reTerminal in horizontal style.
2. For example, with the VLC Player app, you can play a video.
3. A line of vertical misalignment occurs in the image in the window.

Expected behavior
Normal video playback without vertical misalignment.

Screenshots
In the screenshots, the vertical line deviations could not be recorded.

reTerminal (please complete the following information):

• OS: RaspberryPi OS(64bit) 2022-09-06
• Video Player: VLC Media Player 3.0.17.4

Additional context
Similarly, the same symptoms occurred when using OpenCV and displaying with cv2.imshow().

Sorry to hear this. After I check it. I find that it's a problem from the hardware design. We don't connect the TE pin from LCD to controller.So the controller can't do a good job on LCD's frame sync.

Thank you for investigating the problem.
I understand. It's not a software bug.
We hope that the circuit pattern will be corrected as soon as possible.

By the way, if it can be easily modified with a jumper, please provide more detailed information (either a schematic or a picture) on how to modify it.
