I recently upgraded my home pc and work pc to V6 because there was a certain feature I wanted in schematic edditing (in retrospect it turned to be less useful for what I want). I started with Kicad 5 and I found the software to be intuitive from day 1, now it no longer feels that way unfortunately.
I am experiencing on both computers that routing tracks feels incredibly laggy. The pcb editor also fails a lot in getting a track between 2 pads even when there is more than enough space.
It also seems not to register some mouseclicks when I am routing a track. Usually when you route a track, you click on certain locations to force the track to go through that location. The pcb editor no longder does this all the time. I have to click like 3 times before the track stays on the places where I click (bit hard to explain). This often result in releasing the track because I double click too fast.
The last issue I am having (though this is one was also present on V5). Clicking the middle mouse wheel in order to pan sometimes result in unwanted zooms. This is rather inconsistent.
( I recall I had a similar issue with eagle after I hit the update button. At work my mouse wheel can also click left and right. I never use that, but in eagle it resulted in persistant zooming during panning. I was told that this was the new version had a new feature. This new feature for me was a bug so horrible I had to start using a second mouse with different mouse wheel. That was the moment I stopped clicking on ‘update’ buttons in software )
Hope that this feedback is a bit clear/usefull? Or is it needed to make a video?
Are there default settings which are different in 6 than in 5 perhaps?
