On the main site the developers asked for people to report issues. I download LibreELEC (Leia) v8.90.005 ALPHA – LibreELEC ( libreelec-generic.x86_64-8.90.005.img.gz ), create a new installation image and installed it fresh on a empty drive.
In dmesg i get this error: ERROR: CYUVShaderGLSL::CYUVShaderGLSL - failed to open file gl_shader_frag_texture_lim.glsl
Probably some mesa/opengl thing is not right.
Maybe this have something to do with this issue(from dmesg):
WARNING: Failed to get an OpenGL context supporting core profile 3.2, using legacy mode with reduced feature set
