Hi chewitt ,
I have a Beelink SER8 with AMD 8845HS CPU and AMD Radeon 780M GPU and everything plays perfectly except HDR which is too bright and the colors are "off" compared to all my other boxes (AmLogic AM6B+ or Homatics, Zidoo Realtek or Kodi in Windows on the very same Beelink AMD box).
I tried my HDR videos in VAAPI HW mode and in FFMPEG SW mode on LibreELEC 12.0.2 official stable, LibreELEC 13 latest nightly and your version here:
https://chewitt.libreelec.tv/testing/LibreE…-12.80.2.img.gzThe problem is present on all the versions and modes.
In my other thread others said it might be a bug in Mesa or the driver. Since I tried your version of LibreELEC I think I already got the mostly latest amdgpu driver in the process (or maybe I'm mistaking I am not a Linux pro)? So that leaves Mesa possibly being the culprit but I don't know how to get in touch with the Mesa guys.
Are you aware of that problem and is there is a fix for it? Like I said in Kodi in Windows on the same Beelink AMD box the HDR is displayed properly.
If I get an Intel based mini PC instead will the HDR have the same overbright and colors "off" picture or is there a chance they will display correctly?
If so, can I get a very recent Intel mini PC with Arc GPU like this one:
ASUS NUC 14 Pro AI Mini PC, DDR5 5600 32GB RAM&1TB PCIe 4 SSD with Intel Core Ultra 7-155H Processor(16C/22T/24M Cache, Up to 4.8GHz) Intel Arc Gpu/AI GC/AI Boost/AI Ready/Type C 3.2/8K/BT5.3/WiFi 6E
https://www.amazon.ca/Intel-Ultra-7-…z/dp/B0D7M3RD7S
Or is it better to go with an older Intel CPU for correct LibreELEC/Linux support like this one:
Intel NUC 13 Pro, Arena Canyon NUC13ANKi7 Mini PC with Core i7-1360P Processor, Intel Iris Xe Graphics, 32GB RAM&1TB NVMe SSD (12C/16T/18M Cache,Up to 5.0GHz) Support 8K/WiFi6E/BT5.3-Win11 Pro
https://www.amazon.ca/dp/B0DK8JJ249?ref=emc_p_m_5_i_atc
My goal is to SW decode everything up to 8K 60 fps (downscaled to 4K 60fps by LibreELEC) for best PQ so I would prefer the first Asus NUC one with the newer Intel CPU because that would be roughly equivalent to my 8845HS I currently have.
Does LibreELEC correctly use all performance and efficient cores of an hybrid CPU like that Core Ultra 7-155H ? My current AMD 8845HS is a simple 8 cores / 16 threads performance cores and I can see in LibreELEC that all cores are being used and I go up to 60-65% usage with an AV1 8K 60 fps video in SW decoding.
Thanks in advance for your help and support!
Hi there,
Have you recently tested HDR again on your ryzen based mini PC? curious if the issues are resolved because it looks like there were some significant bug fixes near the end of 2025: https://www.phoronix.com/news/Basic-HDR-Radeon-Mesa-VA

I just tried the latest nightly with my Ryzen GMKTEK M6 Ultra. I have the same issues as reported, the gui is always perfect. However sometimes when i start a movie the colors in HDR are washed out, i have to stop and restart then its fine.
