I have noticed for a while that UI seems to lag more when switching from iGPU to dGPU (750m on Late 2013 MBP)

Any one else noticed this?

I'm on a 15" late 2013 as well and notice graphic artefacting (static) upon resume from sleep, opening the lid, and notice severe frame time inconsistency when poking around the OS, at least compared to running 10.12 off a USB SSD.

Funny part is, I don't have dedicated graphics. So even if it isn't the Nvidia Chip's fault, it might be the iGPU

Same problem here (mid 2014). And you do have dedicated graphics. It's the 750m GT.

Want to bet I have dedicated graphics? I'm well aware of the specs of my machine, it's a base late 2013 rMBP 2.0GHz IG. Intel graphics, no nvidia.

I wouldn't be surprised if both types of units have issues.
I believe that your machine does have the Nvidia 750M as VerizonLover said. You can double check by opening About This Mac, then clicking System Report, then clicking Graphics/Displays on the left. You should see both Intel Integrated Graphics and Nvidia 750M on the right. If not, then we might be wrong, or maybe it was disabled through an EFI mod or something.

Doubt it. 2.0 GHz Late 2013 models didn’t have the option for a 750m, only the 2.3 GHz and 2.6 GHz models had the option.

Even then it's an option right? Pretty sure my 4960hq 15" doesn't have the dedicated graphics.
Yeah. There were two 15” models:
  1. MacBookPro11,2 — 2.0/2.3/2.6 GHz, 8/16 GB RAM, 256 GB/512GB/1TB SSD, Intel Iris Pro 5200 graphics.
  2. MacBookPro11,3 — 2.3/2.6 GHz, 16 GB RAM, 256 GB/512GB/1TB SSD, Intel Iris Pro 5200 + Nvidia GeForce GT 750M graphics.
Interestingly enough, maxing out the specs on both actually made the 11,2 more expensive (at least on the Australian store).

And it gets worse.

The first two first are of Terminal open in safe mode, and the second one is the result of running Apple Service Diagnostics.

And no, 10.14.3 did not fix any of the problems from 10.14.3. :(

I would upload the report, but I'm posting from my phone.

Where did you get the test from? I had one I used on my old 2008 MacBook Pro when my Nvidia was failing (luckily it was covered under the repair program). Unluckily, my 2013 MacBook Pro with the 750M also developed problems that I had to pay out of pocket to repair (a cost of $910 AUD). It failed all of a sudden, so I had time to prepare for it. If the test fails, a software update won’t fix it I believe, and you have a hardware issue.

It's definitely the former (You are wrong). Please, I know the specs of the computer I've owned for almost 5 years now (though I've verified my knowledge with your steps), it's got intel iris pro and that's it. And it's experiencing the same kinds of graphical issues the 750M experiences, which is downright weird.

The MacBook Pro "Core i7" 2.0 15-Inch (Integrated Graphics/Iris Only - Late 2013 Retina Display) features a 22 nm "Haswell/Crystalwell" 2.0 GHz Intel "Core i7" processor (4750HQ), with four independent processor "cores" on a single silicon chip, a 6 MB shared level 3 cache, 8 GB of onboard1600 MHz DDR3L SDRAM (which could be upgraded to 16 GB at the time of purchase, but cannot be upgraded later), 256 GB of PCIe-based flash storage, and an integrated Intel Iris 5200 Pro graphics processor with 128 MB of "Crystalwell" embedded DRAM (and shared system memory). It also has an integrated 720p FaceTime HD webcam and a high-resolution LED-backlit 15.4" widescreen 2880x1800 (220 ppi) "Retina" display in a case that weighs just less than 4.5 pounds (2.02 kg). It does not have an internal optical drive.

Indeed. And the glitches even happen when it's running on the integrated graphics
