RE: 9.1.2 Observation - LocalUI.Service - 2800GT - 10-11-2024
I'm pretty sure it is one of these https://www.aliexpress.com/item/1005004199505735.html - 7 inch version, branded as KeDei, and has been "plug and play" up to now
Some more details here https://www.ebay.co.uk/itm/7-Inch-TFT-Capacitive-Touch-Screen-800x480-DSI-Connector-for-Raspberry-Pi-4-3B-/283659988539
I also have the 5 inch version of this screen on a Pi2 running Volumio (not tried Moode on that unit yet)
These screens replaced a couple of official 7 inch screen which both had their touchscreen functionality fail within weeks of each other ages ago while I was still using LibreElec
RE: 9.1.2 Observation - LocalUI.Service - Tim Curtis - 10-11-2024
Here's an update on the "chromium-browser issue".
1. It appears that versions of chromium-browser > 126 cause a "drawing error" to be thrown by XServer on < Pi-4. This prevents the moode knob sliders from showing on a locally attached display.
2. Downgrading to chromium-browser 126 fixes this issue.
After some analysis of the chromium-browser package sets and dependencies for version 126 and the more recent chromium-browser upgrades from Raspberry Pi repos and that ship with moode, it looks like the process for downgrading to 126 is not going to be compatible with our standard Pi-Gen based image builder.
This means that a downgrade to chromium-browser 126 will need to be done via an installable patch script which I'll prolly create for convenience or a manual procedure as described earlier in this Thread.
Moode releases will continue to ship with the latest available version of chromium-browser for Raspberry Pi and hopefully a future version of chromium-browser won't have the drawing issue for < Pi-4.
Also, someone (not me) could post/track an issue to the Raspberry Pi Linux repo https://github.com/raspberrypi/linux/issues?q=is%3Aopen with some details about the issue and the specific xinit error:
"Oct 08 12:18:20 moode2 xinit[11847]: Draw call returned Invalid argument. Expect corruption."
RE: 9.1.2 Observation - LocalUI.Service - 2800GT - 10-14-2024
I'm happy to have a go at posting the issue to the Pi Linux repo if it is as simple as "I'm running xxxx software on yyyy hardware and seeing this error message, and when I make this change the error goes away"
I had a look to see if any similar issue had been logged and noticed the repo landing page says "Kernel issues only" - will they be interested if this is a chromium browser / Xorg error ?

Right, it might be better to post it in the RPI-Distro repo.

Hopefully it makes enough sense

Looks ok to me.

I didn't realize that --disable-gpu also fixes the issue. I'll do some testing on my end and if there's no perf hit or other issues I'll go with that approach for < pi4 rather than a chromium downgrade option.
RE: 9.1.2 Observation - LocalUI.Service - 2800GT - 10-14-2024
No noticeable performance impact on my machine. As Kent mentioned, disabling GPU removes the "tearing / flickering" that was sometimes seen with it enabled
I guess a performance hit might be more noticeable if video playing or 3D rendering was involved, but very little impact when loading a simple web page.

Well, I suspected my rpi 3b, and bought an 4b version. I can restore the rpii 3 then or use it for another project. I find the performance of the rpi 4 with moode latest version a bit unresponsive. The chromium browser uses a lot of cpu at some moments. I can try the --disable-gpu trick or install the older version.
