Interface laggy when editing Waves

Morning . At first excuse my bad english . I am from germany
Now my problem :
since i use Audacity on windows 10 the interface is lagging …espacially when i am marking waves to edit it . I klick with the mouse in the waveform …move it to the right to mark a section and it need a little bit …
I got the when i switched my systems to windows 10 . My computer is a very fast one …enough CPU power an so on .
An its the same with the newest version and older versions …
audio recording is ok …no problem .
Do you have an idea ?

Try reducing the number of colors in the “Compatibility” settings for Audacity.
