In the last few days I noticed that when I update/uninstall mods using Mod Updater, upon reopening the game (manually or via the "Relaunch Minecraft" button), at the bottom left side of the screen, the word "Fabric" repeats multiple times (the amount of duplicates seems to somewhat correlate with the amount of mods that were modified, installed or uninstalled).

This bug does not seem to affect gameplay from the short testing that I did.

Note: The duplicates of the word "Fabric" disappear after reopening the game again.

Additionally, I want to point out that the launching/relaunching process of the game usually takes a minute or more (even for a small amount of mods that are being modified) to finally load, which is quite a long time to wait.

Here are some logs that may help you:

Hello, thank you for the report. The repeating Fabric text is a known issue, but I don't think it affects gameplay. As for long update times, I will look into improving that. Thanks!
