CrowPanel 5.0" (ESP32-S3): Screen artifacts and screen jitter in portrait mode

in Elecrow HMI Display

Product: CrowPanel 5.0" ESP32 Display (HMI)
Firmware: openHASP 0.7.0-rc12 (LVGL based)
Power Supply: 5V 3A (25W External Adapter)
​Issue Description:
I am experiencing significant graphical issues when using the CrowPanel 5.0" in any orientation other than the default (0°). While the display works perfectly in its native landscape mode, applying a 90, 180, or 270-degree rotation causes the following problems:
​Screen Artifacts: When moving interactive elements (like a slider), the screen "jitters" and shows horizontal tearing.
​Ghosting Effect: Pop-up windows (e.g., the IP address info box) leave "ghost" trails or static fragments on the background that do not disappear until another element is interacted with.
​Touch Inaccuracy: When sliding a finger across a slider, other UI elements on the screen seem to "flicker" or react as if they are being touched (Ghost touches/Jitter).
​Troubleshooting already performed:
​Confirmed it is not a power issue (tested with a high-quality 25W power supply).
​Disabled Anti-aliasing and used flat themes (Theme 1) to reduce CPU load.
​Verified that the issue disappears completely in the native 0° orientation.
​Questions to Support:
​Is the RGB Parallel interface on the 5.0" model limited when it comes to software-based rotation at 800x480 resolution?
​Do you recommend specific TFT Timing parameters (HSYNC, VSYNC, PCLK) for the ESP32-S3 to stabilize the frame buffer during rotation?
​Is there a firmware or driver update for the GT911 touch controller and the display that improves synchronization?
​Thank you for your help!

    Try lowering to this. Mine had the same issue and reducing the frequency from 21000000 to 13000000 worked.
    cfg.freq_write = 13000000;
