Well, if you google "kdevelop x11 forwarding" first thing you find is
this https://bugs.kde.org/show_bug.cgi?id=293587 which has the
solution ;)

It's not; I'm fairly certain it has better performance on local
screens than the native one. Additionally, it is more portable
(doesn't depend on X11).
The problem is just that it combines horribly with X11 forwarding. X11
forwarding forwards the draw calls; it basically transfers the code
which draws UI elements over the network, and the actual pictures are
assembled on the other side. This has turned out to be hard to
maintain and unflexible; it is widely considered a legacy way to draw
UI elements. Thus, the more recent way for Qt to draw UI elements is
drawing them into pixel images itself, and then telling the underlying
graphics stack to just put those images onto the screen. This doesn't
work well with X11 forwarding though, since you end up sending a lot
of large, uncompressed images over the network.
