A Screenshot Of Erroneously Large Space Between QToolButtons

STEPS TO REPRODUCE

1. Resize the window to 1⁄8 of 2560 × 1440 px at 100% display scale with a subdivided Custom Tile, like https://bugs.kde.org/attachment.cgi?id=182148&action=edit.

2. Untile the window.

OBSERVED RESULT

The QToolButtons are spaced massively apart, and the QToolBarExtension renders the border area over the already-rendered toolbar in a manner that causes the QToolBarExtension to be nigh impossible to deselect.

This reproduced once, but I've been unable to reproduce it since. Seems like enabling Spectacle somehow fixed it, as it does for a lot of visual bugs. I'll set as WORKSFORME until I can capture a screencast.

A Screencast That Briefly Demonstrates The Erroneously Large Spaces Between QToolBars

(In reply to Roke Julian Lockhart Beedell from comment #2)

Actually, I've managed to capture a reproduction of the QToolButton spacing in a failed reproduction screencast. It appears to demonstrate that merely resizing the window via the Custom Tiling system causes the problem. I've also noticed it for a mere moment whilst moving the window out of a tile, before it fixes itself.
