SBFixes
SBFixes targets a set of inventory and rendering glitches that players report while playing Hypixel Skyblock on Fabric for 1.21.11.
What it does
The mod patches several annoying issues in Hypixel Skyblock, including glass panes that flicker in the Crystal Hollows and inventory glitches where items pop back onto the cursor or drop out of the inventory. It runs on the client alone, so servers need nothing installed. Fabric API is required, and the mod is published for Fabric only, in a single build for 1.21.11. The code is open source under the GNU General Public License v2.0 or later.
Key features
Glass pane fix
Glass panes in the Crystal Hollows no longer flicker or render inconsistently during play.
Inventory glitch fixes
Items that return to the cursor or vanish from the inventory are corrected, so stacks stay where they were placed.
Skyblock-only scope
The fixes target Hypixel Skyblock behavior and change nothing for players on other servers or in single-player.

How it compares
GlassSync is a Fabric client mod for 1.21.5 – 1.21.11 under the MIT License that is open source; it covers glass pane syncing rather than the wider set of Skyblock inventory issues. HSM - Mending fix & Skyblock drill fix is open source under the MIT License and works on Fabric and Forge for 1.8.9 – 1.21.11, addressing mending and drill behavior instead.
