Hey, there,
I have 2 topics with me:

1. On Hypixel skyblock, all dropped items get the glowing effect, but canvas renderer, makes them invisible, here a side-to-side comparison with and without canvas, to show my problem:
   

2. Please make a support discord, where you can quickly ask for help, without having to create an issue, it would really help (me) out!

Thanks!

Thank you for the issue report.

There is already a discord for my mods: https://discord.gg/7NaqR2e. I've added a link to the read me.

This should be fixed by 3cd5d5e - 0c0c275

But grondag hasn't reviewed the code yet. Will close if the changes stay by the next release.

cannot reproduce in latest canvas, looks like the fix was kept @spiralhalo
