CRASH,QCAD with QT6 crashed when operating in main windows on the second screen

Post by kamimail » Wed Dec 03, 2025 3:58 am

hi there,
I have compiled QCAD with QT6 6.5.3 at Win11 using VS2019. when I used QCAD in main screen,everything goes well. but when I move the main windows of QCAD to the second screen (different screen hardware from my main screen) ,edit some entity,like moving a line, it is crashed.
is someone know the reason about the crash? how to fix the crash problem?

the crash reports at QT6GUID.dll!!QLIST<unsigned int>::at(int 64) at line 423 (the first line of the first image about calling stack),it is like triggered by RAction::beginEvent(). I have tested it at QCAD with version 3.32.4, the crash can be recurred.

Thanks in advanced!
