Now this case is different because there is no syntax error or any error in general showing in the log.
What you wanna do to recreate this is:
1) Install the skin below (It has some other skins too but I didn't touch anything as it could affect stuff) and load the "Launcher" one if you choose not to launch it on installation.
2) After loading the skin you should 4 icons.
3) Now move your mouse ON those icons from left to right and visa versa while continuously scrolling down with your mouse wheel. This refreshes the skin and on some random refresh, you will experience what I'm talking about.
It can take a lot of scrolling but it should happen, mine usually happens in around 40 seconds of fast scrolling and not so fast moving the mouse left to right WHILE scrolling. (I'm suggesting that you move the mouse as it activates the Clamp which I think it's what's causing this.)
