Describe your issue

pauseOnHoverDuration was never really consistent, in the sense that sometimes it wouldn't show the icon, despite the cursor being on a split, it would still pause. However < Qt 6.8.0 doesn't get into a stuck paused state. I believe a minimum split size's required to reproduce this, so I included the relevant /settings/*.json files.

OS and Chatterino Version

6830427 built on 2024-11-04 with Qt 6.8.0, MSVC 194134123 Running on Windows 10 Version 21H2, kernel: 10.0.19044

This only happens because the input box is "hidden". Reduced to

#include <QApplication>
#include <QWidget>
#include <cassert>

int main(int argc, char **argv) {
  QApplication app(argc, argv);

  QWidget parent(nullptr, Qt::FramelessWindowHint);
  parent.resize(200, 200);

  QWidget *emptyChild = new QWidget(&parent);
  emptyChild->setGeometry(0, 100, 200, 0);

  assert(parent.childAt(100, 100) == nullptr);
}

Filed QTBUG-131001.

@brian6932 could you check if this is fixed for you on latest nightly?

[brian6932]

1. <= 6.7.2 bug's fixed
2. 6.8.0 bug's not fixed

[Nerixyz]

pauseOnHoverDuration was never really consistent, in the sense that sometimes it wouldn't show the icon, despite the cursor being on a split, it would still pause.

Yea my PR only fixed this part. The other one is a Qt bug.

[Nerixyz]

Fixed in Qt 6.8.1.

[brian6932]

Can no longer reproduce on 6.8.1. Thank you Tom Fors, very cool.
