David Hurka <david.hu...@mailbox.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Version|unspecified |21.04.3 Component|PDF backend |general --- Comment #5 from David Hurka <david.hu...@mailbox.org> --- Thanks. The most relevant source is probably part/pageview.cpp and part/pagepainter.cpp. PageView::paint() might (indirectly) tell Wayland wrong stuff so it does more than necessary. PagePainter paints the document (this is usually the only painting done in PageView::paint()), and has a fast and a slow code path. Maybe the fast path doesn’t work on your system. The repository is at https://invent.kde.org/graphics/okular. -- You are receiving this mail because: You are the assignee for the bug.
