Is it me or is this thread covering two separate issues? 1) Corrupt fonts on interface when using Shadertoy 2) Blocky visuals in particular plugin?
Nevermind my question about the shadertoy plugin, I thought it could be related, sorry for polluting your thread, good luck 
Bump on this. Is it worth sending to ST devs?
They have one. I sent one as soon as the issue was reported, if you’re referring to Vero V.
I need to check in with them.
OK, thanks Sam, I really hope they can find a fix as music with no visualiser just feels wrong. By the way, I’ve experienced this issue on Pi 3/4 Vero 4k+/V. Happy to do any testing required to help further.
OK. If it’s also affecting other platforms it’s not a Mali or OSMC specific issue…
Each of those devices was running OSMC, but I guess nothing else to do but leave it with ST devs at this point?
I think so. Have you tried with Kodi Omega?
Sam
No I haven’t. I’ll test it out when the first stable version of OSMC with Omega is out.
