Created attachment 168878 [details] screenshot showing the transparent rendering SUMMARY The faces are transparent. Rotating the cube as a whole or moving a layer are nearly impossible. Occasionally a face can be grabbed but the rotation is quirky and unpredictable. The version displayed in "About Kubrick" is 1.1.24022 which cannot be found above in the version selection box. STEPS TO REPRODUCE 1. up-to-date archlinux with kubrick-24.02.2-1-x86_64.pkg.tar.zst start kubrick. I tried downgrading to an earlier version from march. but the problem is the same, which leads me to believe, it must be some weird interaction between kubrick and upgraded kde-ecosystem. OBSERVED RESULT transparent rendering, cube cannot be grabbed anymore with mouse and rotated EXPECTED RESULT the old behavior of solid rendering and manipulating the cube with the mouse.

Git commit e38e5a0516088026b071eb2c2a1b6e56ed00136e by Albert Astals Cid, on behalf of Friedrich W. H. Kossebau. Committed on 28/04/2024 at 09:14. Pushed by aacid into branch 'master'. Fix transparent rendering of the cube QOpenGLWidget::paintGL() docs hints that only certain things are reset, which does not include the blending. So any blending functions set are just by chance, and some recent changes in Qt code might now leave other state behind. E.g. the last thing Kubrick's code does is painting the labels, and QPainter font rendering sets the blending src/dest pair to GL_CONSTANT_COLOR, GL_ONE_MINUS_SRC_COLOR. Which then on the next invocation of paintGL() is still set at least with Qt 6.7.0. Resulting in undesired transparent display of the cube (and background).
