--- Comment #9 from Potomac <mister.free...@laposte.net> --- I did a git bisect and I manage to find the faulty Qt5 commit, it's the commit : [9d90c0edac91b35ec96646fd3e6cdd339639ca79] QImage: merge the size calculations with proper (non-UB) checks https://github.com/qt/qtbase/commit/9d90c0edac91b35ec96646fd3e6cdd339639ca79 If I revert this commit then the bug disapears, all is ok, no memory leak with oxygen theme, I created a patch which reverts the faulty commit : https://bugreports.qt.io/secure/attachment/80855/revert_size_calculations_with_proper_non-UB_checks.patch -- You are receiving this mail because: You are watching all bug changes.
