You mean when you move its window back and forth a few times, or do you actually disconnect the external screen?

Do other KDE or Qt applications show this issue?

I've already been annoyed myself by the scaling feature in Win10 but use that OS so little that I don't exactly remember how I got it out of my way (probably set it to 1:1 since I don't have crazy-hi-res screens). Maybe it's worth checking if you can set the scaling of your external screen manually (at the OS level) to something appropriate and see if that addresses the "pumping" effect.

If you (can) build kdevelop yourself you could check if disabling `AA_UseHighDpiPixmaps` (in app/main.cpp) has any effect; you could be seeing an interference between Qt's builtin support for high DPI screens and support already built into the OS.
