Continuous flashing when start application that uses WPF
In the release notes at:
http://www.displaylink.com/filestore...ease_notes.txt I noticed the entry: Windows Presentation Foundation based applications may show corruption or flashing on DisplayLink screens when opened. See http://en.wikipedia.org/wiki/Windows...ion_Foundation for details of WPF based applications. (4825, 4931) I am a user of x1 (www.x1.com). If I use my DisplayLink devices (ViBooks) with rev 6.7 of x1 (www.x1.com) running, I get flashing which is worse that what is described above. With x1 running on my laptop display, this flashing is primarily on two ViBook displays. It starts out as a square flashing that is about 1/4 of the screen area on each of the displays. If I unplug the ViBooks before starting x1, but do not wait long enough, I can also get flashing on the display connected directly to the laptop. Once in this state, I cannot do much of anything. I end up logging out or shutting down. If the ViBooks are not connected x1 runs fine. The ViBooks are fine with the rest of the applications I use. I filed a case with x1 concerning this issue. Rev 6.7 of x1 uses WPF (Windows Presentation Foundation). Here is what I was told: It sounds like this may be an issue with the new UI and it's use of WPF (Windows Presentation Foundation). I have worked around the problem by reverting back to rev 6.2.4 of x1. This was the last version of x1 that does not use WPF. Rev 6.2.4 is running fine. |
