Strange graphical "glitches"

[grpeople]

hi, i recently bought a rock64 4gb board. i tried lakka 2.1.1, but it shows strange graphical glitches like "interferences" in menu and games and generally very low framerates (in this video frames are acceptable if not very good: https://www.youtube.com/watch?v=R5BNIRCjJoM). so i tried another power supply and another hdmi cable, but nothing changed. then i tried ayufan's arm64 bionic-lxde build + retroarch from libretro ppa. it's better than lakka, but problems persist: no in-game graphic glitches, but framerates are lower than video reviews. only the retroarch menu shows minor graphical glitches, like not working vsync and tearing. in general, video performances are not like in video reviews.

ps: i also tried different power supplies and differnt screens.

cheers,
Gioele

I didnt try it yet personally but there is a lot of people talking good things about it, it also includes some minor OC, no idea if it actually need it...

I already tried recalbox. It has less glitches, but it's far from "perfect". In these day I'll make a video showing video output.
