Displaylink 2.3B breaks graphics in 10.10.2 (14C78c)
 

Hi all,

The beta release of 10.10.2 (currently build 14C78c) breaks a lot of graphics based applications (like VLC, iPhoto, Preview and such). I have raised the issue at Apple. They now of the problems, as my call is closed because it was a duplicate.

I now have uninstalled the 2.3b driver of display link, and everything is now in order. Any one else seeing this?

You get a CoreAnimation: rendering error 506.

Regards,
Marc

Yes we've seen the same. Our own bug with Apple is ID #19101518.

Mine problem call is closed as a duplicate of 19081948 (Open). I cannot track this call however with Apple :(

As a possible workaround to the issue, try to connect a DisplayLink device to the Mac and to an external display and to restart the affected applications. This seems to partially solve the issue. Preview and iPhoto correctly render their contents.

Graphics problems persist in OS X 10.10.2 (14C81f)
 

The graphics problems with the Display Link 2.3b and USB32HDDVII persist with
OS X 10.10.2 (Build 14C81f). Uninstall fixes it.

Have you tested with the newest build 14C81h?

I have tested this against the (to my knowledge) latest build 10.10.2 (14C81f).

Have same issue with iPhoto & Preview only option is to remove 2.3 driver, still get rendering issues after restarting applications.

Also get core animation error 506 when open iPhoto or Preview.

re-install yosemite works
 

i tried re-installing yosemite and was able to get preview/iphoto to work, but a couple weeks later it happened again (just get a transparent box of where the window should be) .. googled that is was OpenGL issue, notice that the OpenGL.bridgesupport file had different (newer) last modified date than the rest. I re-installed yosemite 10.10.2 again, and noticed it was now last modified with an older date than the rest of the files (preview/iphoto worked again). i found it in system/library/frameworks/OpenGL/Resources... couldn't upload .bridgesupport file...but re-installing yosemite did re-initialize to file with older date... my mbp is 2009 17" - nvidia 9400M... it only supports up to 3.2 version of OpenGL... it looks like this file maps versions to make them backward compatible etc... I'm no expert, and I'm not sure this is actually why, maybe just lucky coincidence :) .. thought it might help

Thank you Jmoo, this confirms our suspects on the issue. We have got unreliable results too in our testing.
