what's the vertical line coloured by green on the bottom of the run button in IntelliJ?

I am quite doubtful what dose the green line in the white circle that I just marked mean by? Moreover output didn't work when I tried to run it! how can I solve it?

You are using a version control system (Git, perhaps?) to keep track of the changes to your code.
The green bar indicates "This line was added since the last time you committed your changes". Likewise, a blue bar means "This line has been changed since the last commit" and a small gray arrow indicates "One or more lines have been removed from here since the last commit".
This bar does not affect your code or indicate errors or problems. It's only there to inform you which parts of the code you've changed so far and which ones are the same as before.
As for your second question, Stack Overflow discourages users from asking multiple unrelated questions in the same post. You are better off asking that in a separate post.

How to stop IntelliJ from jumping to a subcategory in run console

I hope I can explain my specific annoyance clearly enough:
Quite some time ago, IntelliJ introduced a feature in the run console to parse the content of the output and would try to print a nice tree structure on the left. However, its default behavior of jumping to the error was very annoying. To illustrate my point:
When it starts normally, the full console output is available in the right panel. However, when things happen, or, in my case of gradle run, when I simply stop it, IntelliJ would jump to the specific block of output only with the error:
Note, in the second screenshot, that there is no scroll bar on the right side of the right panel, and thus I cannot scroll up to view the actual run logs. I have to click the left panel's top element in the tree to be able to view all logs.
The locking to a specific block of output is nice to have, but I am happy without it too, as before it was introduced. But the default jumping to that block is annoying and irritating. Almost in all cases I started and ended a run like this, I have to click the left panel to view the whole log -- this "Build cancelled" error block is of no use at all. And when it's jumping to an actual exception, majority of the time I'd need to look around its context for the cause, which requires me to re-orient myself in the log flow where the block was at. This is very counter productive for me.
I have been assuming IntelliJ should provide an option to either not jump to the error by default (leaving the full log available in the right panel), or to disable the whole console output parsing as a whole.
I have not been able to locate a setting for either of this. Does anyone know if that's possible?

Management Studio 2014 doesn't like my Surface Book

It'll install and run but dialogue boxes get all crazy and distorted as to be unusable.
I'm told it's due to my high definition screen.
Any ideas how to fix this?

Gedit with blurry chars

I am using gedit for PHP development but I noticed since a few months that sometimes when I type something, some parts of the text become blurry and only after a click somewhere else or type another letter it comes back to normal. I got used to this problem but I am curious about what can be causing this type of issue. I've tried to reproduce this error on a screenshot but the Ubuntu's screenshot feature removes the focus of the current window, so it "fix" the error on gedit
Do you know what can I do about it?
EDIT:
This problem only occurs in gedit, and nowhere else.
Here comes the picture of the error:
