Scrolling in long files lagging

[AndreKR]

In the following screencast I'm holding the mouse button down and move it up, then stop, then down, then stop, then up and so on:

Note how the cursor does not stay in the middle of the dark area and how, when I start moving in the opposite direction, the scrolling at first continues a bit in the old direction. That isn't how I'm moving the mouse, that is a behavior that is added by CodeGlance.

It seems this happens more pronounced in longer files.

Not a solution, but I switched to "Code MiniMap".

Same here, terrible.

The Code MiniMap plugin mentioned here will be removed:

Seems there is no good alternative anymore. This one worked for a while:

But stopped functioning in recent PHPStorm versions.
