--- Comment #35 from Martin Gräßlin <mgraess...@kde.org> --- Thanks for the log! There are two things in the log which I consider suspicious: * lots of "QPainter::restore: Unbalanced save/restore" - that's probably the breeze deco * QOpenGLContext::swapBuffers() called with non-exposed window, behavior is undefined the latter must be from Qt, we don't use that in the rendering path, so hopefully should not matter. Let's focus on the first issue: maybe try a different window decoration? -- You are receiving this mail because: You are watching all bug changes.
