going from 10.12.3 to 10.12.4 introduced issues - scrambled popup windows

I'm seeing the same thing; here's Parallels 12 and VLC 2.1.1 being mirrored on the native monitor and the DisplayLink monitor.

In the DisplayLink monitor, both apps show garbled visuals.

I had upgraded the DisplayLink driver to version 3.0 and saw this.
I tried downgrading the DisplayLink driver to version 2.6 and I see the same results.

Hi All,

This is almost certainly a regression in the SW renderer in 10.12.4.
If this is confirmed, we can't do anything about this in the driver and it's very important to raise bugs with Apple as soon as possible to get this rectified earlier.

You can use bugreporter.apple,com or if you are in a corporate, ask for a fix from your support representative.
We'll add our own bug ID for these rendering issues to the Sierra list. It was getting much better but unfortunately there are a couple of new regressions now.

Kind regards,
Carlo

I have the same issue on 3x 19 inch monitors.

But for the most part any window dragged onto those monitors exhibit the scrambled windows.

I tried going back to the older driver but that did not work.

Any planned beta's that could address this?

Same issue here. The monitor directly connected to my MacBookPro is fine. It's only the one connected with Display Link. And it's also only when I try using Windows via Parallels 12. So this pretty much kills productivity for me at home or in the office as I have the same set up at both locations. Based on past bugs being reported, how long might this take to be rectified? Really pissed.....

This was posted a month ago and there have been no updates. Mine doesn't work AT ALL with my macbook pro, whereas it used to. I say, either update the driver appropriately, show me how to make it work, or send me my money back... Because this is infuriating, and the product isn't maintaining the standards for and specifications for which it was purchased. I'd really rather write a glowing thank you than a condemning review...

I have a Macbook Pro 13" middle of 2012, and I am still running 10.12.3 which works very well. Does anyone have experience with this setup running 10.12.4?

I don't understand how every single release can mess up so much... Apple seems to be remaking driver code all the time, breaking compatibility to everything you have connected.

So, has anyone with the issues in this thread upgraded to 10.12.5 yet to see if Apple's bug that is causing this has been resolved yet? I'm still keeping my machine at 10.12.3 just to keep my monitors working.
