It has something to do with another QT window below the Hex Viewer.
But it was not happening before at 2ad23ee.
Is the hex window fully repainted every time?

Bisection points to this: d26bd46.

It looks to be an off-by-one (or similar) around this logic
https://github.com/Dax89/QHexView/blob/master/qhexview.cpp#L249
It is not redrawing all necessary lines.
from qhexview.
const int lineHeight = m_renderer->lineHeight();
const qint64 first = firstvisible + std::max(0, (r.top() / lineHeight) - 1);
const qint64 last = firstvisible + (r.bottom() / lineHeight) + 1;
int count = static_cast<int>((last - first) + 1);
This fixes it, but I cannot yet pinpoint to the exact error.
from qhexview.
Here it is
const quint64 firstVisible = this->firstVisibleLine();
const int lineHeight = m_renderer->lineHeight();
const int headerCount = m_renderer->headerLineCount();
const int first = std::max(0, (r.top() / lineHeight) - headerCount); // because all lines are moved down by header
const int last = (r.bottom() + lineHeight - 1) / lineHeight; // round up for fractional line
const int count = (last - first) + 1;
m_renderer->render(&painter, firstVisible + first, count, firstVisible);
Will provide a PR.
