I've upgraded to media-sound/strawberry-v1.0.18 a while back and encountered broken player controls / seekbar. I've downgraded back to v1.0.17 and everything was back to normal. Today, I've upgraded to v1.0.20-r1 only to encounter same issue as in v1.0.18, but now v1.0.17 is not in the tree anymore. I've submitted upstream report (https://github.com/strawberrymusicplayer/strawberry/issues/1283). According to response (https://github.com/strawberrymusicplayer/strawberry/issues/1283#issuecomment-1742060280), issue might be with "... some change in Qt that broke binary compatibility, or some patch applied to Qt that broke it." Not sure on how to proceed or if it's related to media-sound/strawberry, dev-qt/qtcore or something else. Reproducible: Always Steps to Reproduce: 1. Install media-sound/strawberry-1.0.20-r1 2. Open player 3. Start playing track Actual Results: Player controls are broken Expected Results: Player controls should not be broken When trying to rebuild media-sound/strawberry-v1.0.17 (https://gitweb.gentoo.org/repo/gentoo.git/plain/media-sound/strawberry/strawberry-1.0.17.ebuild?id=a43f6105c927ba1a6b622f8702df475ab17e450b) with dev-libs/protobuf-23.3-r2, build fails at ..
