Default Mouse and windows are lagging on third DP monitor

Hello guys
First of all sorry If I did something wrong, I am a new one here, so just learning.
Regarding my issue:
Last time I noticed that one of my 3 monitors is lagging. Particularly 3rd on display port.
When moving for example browser windows or just mouse cursor on 2 others everything is working fine. Sometimes I also have impression that my input from keyboard appears on the screen slower.

All my issues are similar to these which i can see on this video:

I am using:
Hardware: Macbook Pro 15 late 2019,Universal dock D6000
System: Mojave 10.14.6

Today I also updated displayLink driver just normally downloading and installing on top of the previous one

Hello Sylanel,

Thank you for reaching out to us on the forum.

Could you please elaborate on the issue even more?

Are you using 3 external monitors at the same exact time? If so, do other 2 monitors also have this behaviour as on the video clip?

Could you please test using only this one monitor without others and checking the potential lags? Also if possible, please switch the ports where the monitor is connected.

Lastly, please follow this link and gather log files for me for further investigation.

Kind regards,
Jakub

Default Providing additional info

Yes, I have noticed that You have polish first and last name, so we can switch to polish if its ok for You

Yes, I am using 3 monitors at the same time, rest of monitors works currently:

Standard monitor(horizontal position): DELL U2412M
2x Standard monitor(pivot position): DELL P2217

U2412M works currently on DP
2x P2217 HDMI and DP

When I disconnect one monitor so have setup:

U2412M DP 1x P2217 DP - Display is lagging, you can notice that when resizing window(full screen and coming back to partial screen)

U2412M DP 1x P2217 HDMI - Display is lagging, you can notice that when resizing window(full screen and coming back to partial screen) - no difference

U2412M DP 2x P2217 HDMI and DP - Display on P2217 on HDMI is working as expected, another P2217 on DP is having issues

1) No issues on Mac display in any case
2) Sometimes during higher load, those lags are more noticeable and mouse cursor starts to lag as presented on video above
3) It seems also that mouse lags are somehow correlated with some interactivity of website? When website has sth like that mouse starts lagging
4) Also checked the setup on windows and haven't seen similar issues, maybe sometimes like in point 3, but in general browser resizing works correctly

I also have recorded some films and sent you link on email and private msgs so you can understand problem better I believe

Kind Regards,
Sylanael

Hello Sylanael,

Yes, I am indeed Polish but as the forum is international we need to keep the communication in English.

I have contacted you in the private message providing a longer analysis in order to answer all of your questions and material provided.

Thank you very much for your detailed message and videos.

Best regards,
Jakub
