Feedback about driver v3.0 beta 2

However, I might have made an unexpected breakthrough.

The dock, a Targus ACP77EUZ has DVI and DisplayPort video connections. We have all been connected by DVI since day one, but a colleague found me a DP cable to try.

I'm very happy to report that one hour in, everything is absolutely rock solid.

This is a MBP on Sierra 10.12.1, with 3.0b2 drivers.

Thank you Simon,

This is really useful information.
On Monday we'll try your same configuration with DVI connection. Are you all using those Philips 258B6QJEB monitors or are there any others we can try?

Regards,
Carlo

Hi Carlo,

We're all using the same monitors. Some of our users do use a different config with mirroring and their laptop closed, but the hardware is consistent: MBP - Targus - Philips.

Thanks very much,
Simon

I've MBA early 2014 i7/1.7GHz on 10.12.2 + DELL D3100 w/ DL driver 3.0 b2 (just one monitor connected on the HDMI with full HD resolution)

I tried different combinations:
DL 3.0b2 + OS 10.11.6, 10.12.2

The DisplayLinkManager goes crazy every second day and uses >100-110% of the CPU, event with no windows or application running on that desktop.
Other colleagues experienced the same problem with slightly different configurations.


Best,
V.

The "White squares" become annoying! I am not able to see when I receive a new email and I missed a call because my screen (Chrome) was WHITE. I cannot "click it" each 2 minutes.

Please fix this as soon as possible!

Don't forget Carlo's suggested temporary workaround for the artifacts/window paint failures:

1. Open System Preferences
2. Click on Mission Control
3. Make sure "Displays have separate Spaces" is checked

I haven't had any artifacts or paint failures since enabling this option. I don't typically prefer to run with this option selected, but it's better than the alternative with the current DisplayLink driver! Hopefully it doesn't make WindowServer super unstable for you like it seemed to for @luckman212 (it hasn't affected stability that way for me as far as I can tell).

Just came to report that I installed the 10.12.3 (16D32) final yesterday and still have the same artifacting as before, so Apple has once again left us hanging it seems.

3. Make sure "Displays have separate Spaces" is checked

sorry. but this is not a really viable option. it does not allow a window to span multiple displays.

I totally agree with you.

With the current driver, it's more of a pick-your-poison situation than an actual workaround. If you don't typically have windows that span multiple displays, then you might prefer this to the artifact/repaint issues at the cost of the other shortcomings of enabling that option. On the other hand, if you need windows to span multiple displays, then you're stuck with the artifacts/repaint.

Unfortunate and annoying, I hope it gets resolved satisfactorily soon!

Having an issue with colors seeming very washed out. Greys are hard to see and kind of just blend with whites. Anyone else have these issues?

I'm seeing high CPU usage (90-100%) for the DisplayLinkManager task with 3.0 beta 2 drivers on Sierra (10.12.3)

MBP (Late 2013, 13") Intel Iris Integrated graphics
Kensington SD3500V dock driving 2 displays, along with Mac Retina panel for a 3-diaply setup.

Anyone else seeing this high CPU usage which I thought we'd seen the back of some time ago? It's certainly new (again) for me, but can't be sure which of the upgrades (displaylink drivers or OSX) I've applied recently has caused this.

Can I provide any further info for debug purposes?

Rob.
