[X2Go-User] How to make the picture smoother

hi all， I'm using x2goclient v.4.1.2.2 for windows, connecting to CentOS 7.9 x2goserver 4.1.0.3. When I open the CAD software on the remote desktop and drag my model, the picture is not smooth, and the image display is very jumpy. The client parameters I use are Connection speed: ADSL Compression Method: 256-jpeg Image quality: 0 display width: 2560 height: 1449 DPI: 80 I tried adjusting these parameters and found that there is not much improvement, but if I shrink the remote desktop window, it will become very smooth.

Is there any method or parameter setting to make the picture smooth? Hope someone can help me. Thanks.
