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!

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

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.
