Menu rendering/drawing issue on RPI4

reefer · February 9, 2021 at 11:24 PM

Hi All,

I have strange menu behavior on my LibreElec installed on RPi4.

When I browsing menu I can notice it redrawing. It looks like blinking or half blinking of menu items when quickly running through main menu from first to last item(actually no difference what menu items are active, they all are affected).

The most strange thing, that on my PiZero menu browsing runs perfectly smooth.

Besides this issue I have no problems with RPi4, I can watch 4K video, or use Elementum plugin without problems(which is the problem on PiZero sometimes).

I've reinstalled from scratch several times and changed SD card(but the same manufacturer actually) with no luck.

What can help me?

Official:Forum rules/Banned add-ons - Official Kodi Wiki <= no further support while you have banned add-ons installed. You will need to provide logs showing a clean system before anything else happens.

Well, ok. I’ve reinstalled it again from scratch. Now it has no add-ons at all. The issue is still there. What logs should I provide and how should I collect them?

Thank you.

Please provide a full debug log.

How to post a log (wiki)

1. Enable debugging in Settings>System Settings>Logging
2. Restart Kodi
3. Replicate the problem
4. Generate a log URL (do not post/upload logs to the forum)

use "Settings > LibreELEC > System > Paste system logs" or run "pastekodi" over SSH, then post the URL link

here is log: http://ix.io/2OWg

and here is crash log if applicable: http://ix.io/2OWh

I've replicated the problem by browsing menu quickly, but I'm not sure it's visible in logs.

Well, I've tried one of the latest but with no luck. Could you please share the version you use.

Hi All,

Just in case someone still wants to help I recorded a video of menu behavior. Here it is:

Meanwhile I changed hdmi cable, changed power supply to 5V/3A and reinstalled Libreelec to new ultraspeed card. Nothing helps. Issue is still here.

Can you check on the monitor/TV's info which actual resolution and refresh rate is being used?

**HiassofT** · February 24, 2021 at 8:20 PM

reefer in case you are using LibreELEC 9.2 - yes, the issue is well known, and no, it won't be fixed in LE 9.2. LE 10 nightly builds don't have the issue.

so long,

Hias

Klojum , HiassofT , thanks, you actually both were right. I had 4K resolution in settings, when changed to 1920 it gets better(yet not perfect as for me). The point is that LE10 is not working with 4K at all, so I had to switch to 1920 and it works same way as 9.2 on the same resolution.
