This sounds like display driver issue, more specifically DE2 driver. I'm aware of one unfixed issue but it shouldn't be visible like this. I would need to reproduce it to figure it out...
Sometimes it happens after a few minutes, sometimes it takes longer. I made some photos to show what's happening. First photo is 4:3 vid, second a movie and on third pic only thing that cn be seen after I scroll through menu.
Yeah, I saw such issues when there was a bug in display driver when using more than one plane. In this case video is one plane and GUI overlay another. For some reason overlay plane gets clipped to the visible size of video plane.
Can you tell me more about your setup? What is your display resolution and refresh rate? What is the frame rate of the videos which can cause this issue? Board is OrangePi PC, right?
Display is a Samsung TV, 1280x720, 60 Hz. Vids are usual 24/25 FPS, nothing fancy. I grabbed media info screens from MPC, hope it helps. Yes, I have Orange Pi PC.
Add correct lines to scripts/uboot_helper. You have to create H2 section and add your board. Then copy project/Allwinner/devices/H3 to H2. After that, you're on your own
Please help me man!
I'm wondering what in the statement "not supported" was unclear?
Lewis I reproduced the issue and I already know what is the problem. I'll take a look how to properly fix it in following days, but for quick fix you can execute:
Codedevmem 0x01100800 w 0x301 devmem 0x01100008 w 1during playback, when issue appears.
Thanks jernej, this was super fast. Have you already included the fix into the latest nightly because on my main 1920x1080 Toshiba TV everything works great without any issue. Haven't tried it on the old Samsung TV.
No, nothing is merged yet, but I have working patch already. I probably also discovered reason for green frames - also DRM driver issue. I didn't know about these issues because I always tested on 4k @ 30 Hz where it seems to work fine. However, if I switch to 1080p @ 60 Hz, then I'm able to reproduce these two issues quiet easily.
Strange, I decided to try LE on my main 1080p @ 60 Hz TV to see will it be the same thing as on old Samsung TV but in these 2 days of testing everything is working flawlessly, no menu disappearing, no green screens, CEC is recognized out of the box (on Samsung it doesn't work). I would say it's on pair with official LE 9.2.3 for Raspberry Pi 3.

if the board was the same cpu why don´t herlp to compile what if the problem? i don´t have money to buy 1gb board 
[user = '26200'] Lewis [/ user] Pruebe esta actualización: LibreELEC-H3.arm-9.80-devel-20200719123645-ddd7a12-drmfix.tar

Lewis Please test this update: LibreELEC-H3.arm-9.80-devel-20200719123645-ddd7a12-drmfix.tar
it should fix disappearing menu and green screens in all configurations.
Tnx jernej, will try it as soon as I come back home.
Please help me man!
First of all follow the wiki to get a build environment: Compile [LibreELEC.wiki] -> Stop at "Choose the PROJECT and ARCH to compile"
If you have done that, you should have a directory structure that is the same as the LE github page: GitHub - LibreELEC/LibreELEC.tv: Just enough OS for KODI
What jernej is trying to tell you is:
-> Add correct lines to scripts/uboot_helper: open the folder scripts and search the file uboot_helper.
example: LibreELEC.tv/uboot_helper at master · LibreELEC/LibreELEC.tv · GitHub
In this file you will see all supported allwinner boards. Add the lines for your board. The correct name should be the same of the linux dts file and adjust it to resemble the other lines in the file. Look here: linux/arch/arm64/boot/dts/allwinner at master · torvalds/linux · GitHub
-> You have to create H2 section and add your board. Then copy project/Allwinner/devices/H3 to H2. After that, you're on your own:
go to your start directoy and browse to the folder /projects/allwinner/devices/
example: LibreELEC.tv/projects/Allwinner/devices at master · LibreELEC/LibreELEC.tv · GitHub
Make a new folder for H2 and copy the stuff from inside H3 to the new H2 folder.
Proceed the wiki Compile [LibreELEC.wiki] starting from
"Choose the PROJECT and ARCH to compile" and use the allwinner H3 example as base. Should be something like this:
PROJECT=Allwinner ARCH=arm DEVICE=H2 UBOOT_SYSTEM=(your_board_name_from_uboot_helper) make imageNo guarantee it will work so from there you are on your own.
If this is all to complicated, buy yourself a new board that is supported.
Lewis Changes were already merged few hours ago so next nightly image should have all fixes. Anyway, I'm still interested if it works for you or not.
Tested 20200724 nightly image over the weekend without a single issue. Menus are not disappearing, no green screens, nothing. Great job jernej, many tnx. I think I'll repurpose more Opis with LE for family members, it's production ready.
