<![CDATA[MESA issues - mm actually displays]]>Saw this error in npm start. Quick search says that these typically rnder a black screen - I am actually seeing MM, so what does this error mean?

add

export ELECTRON_DISABLE_GPU=1

to the place where you do
npm start

add that line before the npm start

in next release Jan 1,
we are doing this by default a d adding a new
ELECTRON_ENABLE_GPU=1

as no one is really using the GPU

If you’re getting your mirror up on screen, there’s no issue.
