--- Comment #11 from Christoph Feck <cf...@kde.org> --- KMail uses the Chromium web engine (via QtWebEngine) to display mails. This web engine internally uses OpenGL from multiple threads, which the Nouveau OpenGL driver fails to handle. Other KDE applications do not use QtWebEngine. -- You are receiving this mail because: You are watching all bug changes.
