MacOS – How to never see scroll bars

I suspect the blurring of text is caused by a low-memory proxy being used to ensure high FPS during scrolling, especially on Retina machines, probably when using integrated Intel graphics.

Therefore I would suggest doing the following steps in the below sequence, in order to maximize available RAM and VRAM:

• close all windows in all apps

• quit all apps

• disconnect any external monitors

• close extra desktops in Mission Control

• for machines with NVIDIA GPU, make sure your computer is plugged into the charger, or that Automatic Graphics Switching is turned off in Energy Saver

• if on a non-Retina machine, set "Best for display" in the Displays settings

• if on a Retina machine, set "Best (Retina)" in the Displays setting

• restart the machine or open Terminal and type "sudo purge", the hit enter, then quit Terminal

Note: the purge command takes a minute or two to finish. I've found it can really help to clear up RAM. Restarting does the same thing. Sometimes RAM does not automatically get freed up like it's supposed to without these steps, at least on 10.8.5 and earlier. It may not apply to 10.9 and newer, but it can't hurt to try.

If you would please, both before and after completing the above steps, open Activity Monitor and take note of how much memory, CPU, and disk data per second is being used. Post your before/after figures for Physical Memory and Memory Used in the comments (or Free memory if it shows that). Also let us know if the steps resolved your issue.

I too have this issue. If you stop scrolling for 5 seconds because your reading, then go to start scrolling again, there is a freeze or delay of about 1 second. its noticeable, and very annoying. There are no viruses, and its not a plugin. (I don't use chrome extensions or plugins.) Safari doesn't have the issue, and its machine specific. The identical Chrome on an older iMac, identical OS, doesn't have the issue.

My guess is that chrome has "frozen" the page, to save on CPU cycles, and has to release that and start live rendering it again when it sees you start scrolling. Or maybe its a delay of swapping between graphics mode on the hardware...?

Some interesting extra notes...if a text editor panel is open, such as the one you comment on here, the issue does not exist. If an active video such as on youtube is playing in the window, then there is no lag scrolling either.

If you are scrolling up, there is never a delay, its only scrolling down that has the delay.

You see the mouse pointer change for the items that would be scrolling under it before you see the page even move. So this indicates its some lower level thing that is going on, and most likely graphics related.
