Cursor lags in apps

Hello! I have a MBP 15 (late 2013) with integrated graphics - Intel Iris pro and faced such a problem (see video): in any app when the cursor switches from an app into system appearance (for example from brush into a system arrow in Photoshop) I see strange bands across the display. This lag do not appear on Mavericks OS, but on all future versions of the Mac OS system (now I have 10.13). I tried to reset SMC and VRAM - it didn’t help.

Any ideas how to solve this problem?

MacBook Pro with Retina display, macOS Sierra (10.12.4)

Hi,

To start up in safe mode:

Start or restart your Mac, then immediately press and hold the Shift key. The white Apple logo appears on your display. If you don't see the Apple logo, learn what to do.
Release the Shift key when you see the login window. If your startup disk is encrypted with FileVault, you might be asked to log in twice: once to unlock the startup disk, and again to log in to the Finder.

To leave safe mode, restart your Mac without pressing any keys during startup.

Then see if that makes a difference.

I noticed one interesting thing about this lag. It is sometimes ( lasts 2-3 seconds) "break" the interface of the photoshop.

That is why I think this lag somehow connected with the graphic driver, because hardware problems can't cause such strange behavior of the interface of the program I believe. What do you think?

Try stress testing your graphics chip by using the program I have linked to. Open the program and click "Run stress test".

Download GPU Test 0.7.0 (Free) for Mac OS

If doing that causes your Macbook to either crash or show a lot of weird stuff on the screen, that's the graphics chip that's going bad.

Thank you for your advice

I run this software and made couple of tests (FurMark OpenGL 2.1/3.2 and TessMark X64 OpenGL 4.0) for 5 minutes. Everything seems OK.

I do some rendering in Blender time to time (it is a 3d modeling app) and also to not see any problems.

5 minutes isn't a lot. Let the test run for something like 2-3 hours. If you still don't get anything weird you may want to go to Apple and ask them to run an "Apple Service Diagnostic" test on your computer. That will tell you if there's a problem. Only Apple are supposed to have those tests, so you'll have to go to them to have it checked.

Thank you for the quick reply

I just entered the safe mode and didn't notice any cursor lags in Photoshop (in safe mode) but when I restarted the system in normal mode then the lag appeared again.
