Hello,
Can somebody please tell me how to fix this? XD
It appears only when the object is zoomed out.
I don’t know what this is because the image is small. 
The scale problem is mostly solved by initializing the scale.

if this only shows up in the viewport and not in the render then you do not have to bother about it.

In general it could be something about clipping range. Or especially for the text object: a too big depth in the bevel option…
hello, thank you. this actually shows in render.
sorry. I couldn’t post the whole photo because of privacy reasons.
This is a bit weird… it looks more like using some kind of image (dirt/usage ) texture and not like some overlapping geometry… but your material doesn’t show any image used.
When trying to zoom in i can see something like ventilation slots on the left side and something blue behind them. Also on the top right something dark green beneath.
You are sure you are showing the correct materal slot… this seems to look more like some image texture with alpha ?? Or even some wholes in the geometry ???
There are no factors in this configuration that can affect the scale.
Isn’t it a matter of modeling or there are other material settings 
After seeing this i recognize that it seems i was reading something totaly different before…
Computer gremlins had hidden the …ure right before my eyes…
