Flickering taskbar

Wilson_Energy · 11-10-2019, 07:24 PM

I have a Wavlink USB-C Dual 4K Docking Station (WL-UG69DK1) attached to a Lenovo Yoga C940. Recently I was having trouble with the external monitor switching to low/incorrect resolution when I re-attached the laptop to the docking station.

I went to the Wavlink site and installed DisplayLink 9.2.

Since I have installed that, when waking from sleep, the taskbar on my laptop monitor sometimes flickers and is basically unresponsive.

I've found a workaround is to turn on autohide in desktop mode then turn it off. That fixes things. But it is a big hassle to do that every time I wake the laptop.

Any ideas?

Hello,

Peculiar. The DisplayLink driver does not see objects or windows, therefore we don't see a taskbar, we get the pixels from the GPU.
Flickering has different meanings for different people. If you could have a video taken on a smartphone of the defect, that could tell us more from the type of flicker. Subtle differences can help find out.

I would recommend checking if there is a new driver for your graphics card (GPU).

Kind regards,
Alban
