7740/RTX4000/U3219Q display artifacts in linux

I just received a new 7740 with Quadro RTX 4000 GPU... Everthing works fine in windows, however in linux i keep getting display issues when using the WD19DC docking station in mint linux.  Monitors are Dell U3219Q 4k displays.  All the latest nvidia drivers installed (435) etc...

it looks like the following...

Frustrating video output 

i've tried different monitors and docking stations  (all same models as above), different resolutions and refresh rates (30 and 60)... it keeps displaying the same.  However the artifacts change as the screen changes.  If i take a screenshot, the artifacts aren't captured.  It just seems to be at the hardware level.

Any thoughts??

Re: 7740/RTX4000/U3219Q display artifacts in linux

Update:  i have a workaround.  Originally, i was using DP from WD19DC dock to U3219Q monitor.  I changed cabling to a DP to HDMI adapter to HDMI cable to U3219Q.  I no longer have the artifacts happening.

Hope this helps someone...
