I've noticed that after opening the GUI, when I move the mouse over different items, the tooltip (which displays the materials required for the current item) flickers at a high frequency, making it very difficult to use the GUI. Moreover, I observed that about half of the area on the icons of the items located at the edge of the GUI causes this flickering effect when the mouse hovers over it, while the other half does not have the same issue. There are no error messages, but this makes the GUI hard to use. I tried switching between different game aspect ratios and languages, but the problem persists, which is quite strange.

Furthermore, there is another bug. If I install this mod in a game save using a particular language and then save the game, switching to another language and loading the game again results in an error when opening the GUI. Below is the error message.

The mod Quantum Fabrication (2.2.1) caused a non-recoverable error.
Please report this error to the mod author.

Can you take a screenshot of GUI position during which flickering occurs? And a screenshot of the tooltip too. The flickering shouldn't happen under normal circumstances.

I'll see what I can do about the language thing.

GUI screenshot，the part inside the red box will not flicker while all other parts are flicker ：

screen recording of the flickering issue, during the recording, my mouse did not move, and the flickering effect was much faster than what is shown in the GIF：

I have already tried uninstalling all other mods, but the issue still persists.

Ok, I found a problem. I might fix it tomorrow.

Fixed in 2.2.2.

I was about to report that, thank god!

I love the idea behind this mod, its pretty cool.
