Hi there
What was the solution?
I got the s as me… exactly the same ! 😤
Thank you for you feedback
Srv

It seems that I cannot edit my previous post, so I create new posts for my updates and additional findings:

I played around a bit and found out that the issue seems to be related to large pictures, maybe in the area of 3000x2500 px, with some being around 2500x3500 px.
On the other hand, resized to 200px height, these pictures did not crash the current version's Kodi, even when using progressive. Baseline did not crash Kodi, either.

As now, I would recommend to resize pictures to a max of 4 megapixels.

Discourse:
This reminds me of back in the day, using XBMC on the original XBox, which also had issues with pictures > 6 megapixels. But it did not crash and instead simply not render the pictures at all.

Can you create a step-by-step installation with screenshots?

Ok, so if RecalBox 7.2.2 works for you, stay with it

Looking forward to this being resolved so I can finally dust out my RPi4 recalbox and enjoy x265 hardware decoding. For now, sticking with my Rpi3B+ on recalbox 7.1.1 as my daily setup.

So I assume that you own a Pi 3b+ in a Retroflag Case with working Recalbox 7.2.2 on in and a Pi 4 to.

If that's so, "dust out" the Pi 4, get a SD-Card and install LibreElec on in, and use the Pi3b+ in the Retroflag Case for gaming.

Or did I get it wrong ?

If the Pi 4 is in the Retroflag Case, than where is the Pi 3B+ you mentioned ?

If the Pi 4 is in the Retroflag Case, take it out,
buy a simple Case

a Powersupply

and maybe a HDMI-Cable

and installe LibreElec.

That's way better than waiting for other Things that (maybe) will never happen.

Update:
Lowering the UI resolution down to 720p seems to have done the trick, the glitch appears very rarely now.

I guess you can lock the thread now.

@zing Thank you for this information. I will look through those tutorials.

Is it possible to install Recalbox and LibreElec as Dualboot on a PC ?

Theoretically yes, it is possible to dual boot between any 2 operating systems.
But, we do not recommend dual booting Recalbox with any other system, the ideal is to keep Recalbox separate to ensure that one system does not interfere with the other and cause any unwanted headaches.

As we don't recommend it, we don't have official documentation for this (although there are some tutorials from some users who were interested and did dual boot, which you can use as a base).
