| ELB-1419 | Fixed | Parallel RGB Video Playback Issue | Colibri iMX8X | RGB, VGA, Video Codecs | | Low | No |
Description: Parallel RGB which is also what drives the RAM DAC towards the DVI-A or VGA ports on the Colibri Evaluation Board or Iris is using mxsfb-drm which currently fails g2d with the following error:
dpuv1/dpu_lib.c:197 open file error.
g2d_open: Init Dpu Handle fail !
It's currently unknown how one could play hardware accelerated videos without using g2d. Workaround: Using LVDS or MIPI DSI as available via FFC connector on the back side of the module (e.g. also with the Colibri iMX8X DSI to HDMI Adapter) is using imx-drm which works fine. |

Description: Support parallel RGB displays |
| ELB-5303 | Known Issue | Flickering Artifact On Display Connected To DPI ADMA LCDIF Interface | Colibri iMX8X | RGB | | Low | No |
Description: When using the “fsl,imx6sx-lcdif” (ADMA LCDIF DPI Interface) driver and playing a video, using the GPU, or having some high memory load some display artifacts can happen because of bandwidth issues. This is not happening with 800x600 resolutions or lower. Workaround: Use DPU ( "fsl,imx-lcdif-mux-display" driver, display_lcdif) as a display controller
or
Use a 16-bit frame buffer (e.g. `gbm-format=rgb565` in weston. |
| ELB-3219 | Known Issue | Artifacts on the Left of Parallel RGB Screen | Colibri iMX8X | Graphics, RGB | | Low | No |
Description: We saw minor artifacts in the form of approximately 5mm long grey 1px high bars that are randomly blink on the left side of the screen. This issue depends on if either &display_lcdif or &adma_lcdif in device tree. |
