    Please run it in the debugger as @aha_1980 suggested to get a proper backtrace so you can see why the assertion is hit.
    The reason why it works in release mode is that there are no assertions active - assertions are a pure debug helper stuff

      @Christian-Ehrlicher

      Am I missing something about the debugger?

      Thanks.

        You have to go up the stack in the stack trace window...

          @Christian-Ehrlicher - I never did figure it out. tried watching youtube videoes to see what I am missing. I am just going back to an earlier version because it's not breaking at the excepting it's just dying in the main. And when I Retry I am not getting the same error point in QT Creator.

              @mrjj I am not sure Qt is providing the Traceback.

              The application just quits with a C++ Error. Here is a video. I have to Abort, Retry or Ignore.

              I am not quite sure if I select Retry, I am getting the correct info from the Stack Trace.

              If you have any advise, it would be helpful.

                I have finally created a reproduce-able issue with an example.

                Here is the video

                https://www.eatoncode.com/resources/shareit/Desktop_2019-02-02_23.44.44.mp4

                Here is the code.

                https://www.eatoncode.com/resources/shareit/buttonqt/demobuttons.zip

                So far it works from 5.9 - 5.11.3, but it breaks on 5.12.0, 5.12.1 and 5.13.0 Alpha

                In debug mode, I get the xData.data error but I can run in release mode but the hover images do not display correctly on my buttons.

                I am using MSVS 2017 32 and 64 bit versions.

                Thanks for your help in advance.

                  From my pov this assert was there already in the previous version but you never used the Qt debug libs.
                  The calculation for the assert looks wrong to me - I've created a bug report: https://bugreports.qt.io/browse/QTBUG-73472

                      It appears this bug was fixed in 5.12.3 and works in 5.12.4 But does not work correctly in 5.13.0.

                      Can we carry over the bug fix from 5.12.3 and include it in 5.13.0 ?

                        There is a daily merge from 5.12 to 5.13 to dev so it should appear in 5.13.1.

                          Correction...

                          The fix was on 5.12.3

                          Looks like it's broke on 5.12.4 again.. for some reason it looks like this.

                          https://www.eatoncode.com/resources/shareit/qtbug_73742_2019-06-24_07.18.28.png

                          At least there is not a fatal error, it's just NOT displaying correctly according to the docs

                          Buttons works on
                          5.6.X - 5.11.X
                          5.12.0 - 5.12.2 - Broke with Error listed above.
                          5.12.3 - Buttons work perfectly again
                          5.12.4 - No Error But Example has display issues with 4 square backgrounds. (See above screenshot and movie clip)
                          5.13.0 - Has same fatal error as 5.12.2

                          @Christian-Ehrlicher - Ok, I will be checking out 5.13.1 once it comes out. Thanks for the help.

                            @Christian-Ehrlicher I updated my Qt because of a maintenance update. Now it seems that 5.12.3 is not working.

                            Is this truly a bug or should I use a different approach?

                              Hi @EatonCode,

                              You should report the issues on https://bugreports.qt.io/browse/QTBUG-73472

                              That is the only way to reach the responsible maintainers.

                              Regards

                              Qt has to stay free or it will die.

                                @aha_1980 Hey Thanks... I was not exactly sure I could place or update a bug request myself. But obviously, I can. I uploaded the current bug request.
