esp32c3驱动240×240 ST7789 LCD设置y方向镜像后部分花屏 (IDFGH-13171)

[swjqq]

Answers checklist.

• [ ] I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• [x] I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• [ ] I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

esp_lcd_panel_mirror(panel_handle, false, false); 不设置y镜像时正常显示； esp_lcd_panel_mirror(panel_handle, false, true); 设置y镜像时部分花屏。 idf版本：5.2.2，详细代码如下：

你需要在刷新屏幕时，增加Y偏移量，但是在LVGL这部分驱动可能在固件内部 You need to increase the Y offset when refreshing the screen, but in LVGL, the driver may be internal to the firmware
