I installed RPI4 arm 9.1.001 on my Rasberry Pi 4 and everything is very lazy and slow. Moving between menus is not smooth and just ugly.
After some time in Kodi appeared a thermometer in right corner, so RPI is burning.
With Noobs is not possible install Raspbian and LibreELEC, Noobs doesn't recognize LibreELEC image.
Tearing in the GUI is a known issue.
It's best to run the Kodi GUI at 1080p rather than 4K as this will result in snappier performance (Settings > System > Display > Limit GUI Size > 1080p).
RPi4 shouldn't be overheating in normal usage, you can try running bcmstat.sh to monitor temperatures.
It's possible that NOOBS needs to update with RPi4 support (guess, as I've never used NOOBS).
Any plans to do version for RPI4 faster and smoother? Or I'm just using wrong version?
This version is unusable with RPI4
Yes, this is the first release on brand new hardware, of course things will improve. As mentioned in the blog, this RPi4 release is essentially an "alpha" release. The feedback from this and subsequent releases will lead to improved RPi4 kernel and firmware support which will be a huge benefit to LibreELEC with Kodi 18 and, eventually, Kodi 19.
To be totally honest I have found the RPi4 version of LibreELEC 9.2 to be entirely usable, and stable. I'm confident the more obvious issues will be addressed quickly.
