An update to crt-super-xbr. It now uses crt-hyllian-multipass and became much faster. Other than that, there’s a glow version (first release). I’ve managed to fix some weird artifacts from old versions, it’s now much lighter (it uses linear gamma since first pass now).
crt-super-xbr and glow + crt-hyllian-multipass (slang)
