rendering issue with Qt 5.9.6?

[René J.V. Bertin]

Hi,

I'm upgrading to Qt 5.9.6, and see a rendering issue in KDevelop where document views don't size to the entire parent view width. 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.

I see this on Mac, with the Cocoa and with the XCB QPA plugin. I haven't yet had the time to build Qt 5.9.6 on my Linux rig.

I don't think I'm patching anything in KDevelop that could cause this, but just in case, where would I start poking to trace the glitch?
