going from 10.12.3 to 10.12.4 introduced issues - scrambled popup windows

Wait wait wait I've got it back.
If I turn on "Automatic graphics switching" off in the Energy Saver preference, I can reproduce the issue. Turning it on again resolves the issue the next time the window is on the DisplayLink screen.

Point is, we already tried playing with this setting before the SMC reset and it did not make any difference either way. Definitely an inconsistency about deciding which GPU or SW renderer is rendering which buffer.

So YMMV but it would be interesting to know if any affected system on the forum does NOT have a discrete GPU.

Will update Apple with the finding.

Kind regards,
Carlo

I have a 2011 MacBook Pro 15" with two identical monitors connected, one via the miniDisplay port and one via the USB port using DisplayLink. Several applications, including Word 2016 and Parallels desktop exhibit extremely slow response on the DisplayLink-connected monitor, but are fine on the other monitor. I have file bug report 31605058 with Apple. This started happening after installing MacOS 10.12.4.
