I'm not getting that in Kate, and a rebuild of KTextEditor (5.42.0) doesn't change anything in this regard. I'm currently rebuilding KDevelop itself but I expect this is a runtime issue, not something related to compile-time constants.

What I'm seeing is a document view that is scaled as if the right and bottom docks are expanded (but they aren't; my left dock always shows the project manager). I can restore the proper view by opening the right or bottom dock and then changing its width/height. Idem when I change the left dock width. But as soon as I switch to another document I have to start all over again. It's a bit as if the initial view size calculation uses the information about the docks that is not up-to-date, but curiously it continues to use the wrong information when I resize the entire KDevelop window or toggle fullscreen mode.
This reminds me a little bit of something I could call the "negative" of this glitch: sometimes when I open KDevelop, a bottom dock widget that should be expanded according to its button state is in fact not expanded at all (or else covered by an open document).
Thanks for any pointers...
