--- Comment #4 from Alex Rozkov <ralex2...@gmail.com> --- (In reply to Nate Graham from comment #2) > Cannot reproduce with my dual-screen setup, but it's an assert not a crash, > and it's in OpenCV (a dependency of Spectacle) rather than Spectacle itself. It's a spectacle bug in the following function: https://invent.kde.org/graphics/spectacle/-/blob/master/src/Platforms/ImagePlatformKWin.cpp?ref_type=heads#L123 OpenCV assert checks parameters of mainMat and rect. Especially rect.x + rect.width <= mainMat.cols must be true, but it isn't (4431 + 6400 > 10830). I attached screenshot of backtrace with this info -- You are receiving this mail because: You are watching all bug changes.
