--- Comment #11 from Blazer Silving <breakingsp...@gmail.com> --- Yes, the Firefox top-most resizer issue is definitely upstream. I'm still gathering information before submitting a report, but I'm not sure Firefox has the ability to read the window hints that Kwin uses when tiled. While removing the resize 1px buffer does partially resolve the issue, the proper way is to read the tiled state and act accordingly. That's going to be my next place to investigate and will require a full kwin debugging setup. In fact, with latest Google Chrome/Chromium and the patched Firefox, I cannot replicate the untiling bug in X11 or Wayland for any other application. These browsers are likely the only cause of this bug because of their unique tabs-on-top decoration. I might record a video of the Firefox behavior to ensure we're discussing the same bug, but it looks like Chromium is fully fixed in this regard. Chromium has changed much with their new UI, so I suppose a fix was included there for the edge case I noted a few months ago. -- You are receiving this mail because: You are watching all bug changes.
