I dont konw why.how to fix it .is that a bug?

Christian Ehrlicher

@nicker-player said in when running the code of webengineview,came the errors:

.is that a bug?

How should we know? You posted some error messages but no minimal, compilable example so... no it's not a Qt bug but a bug on your side - prove us wrong.

nicker player

when I resize the qwebengineview,the errors came out.I guess maybe it was caused by the chorum ui threads.
cause When I resized the qwebengineview very quickly then the program crashed.heres the detail information.

by the way.are there any ways that could resize the qwebengineview normally?
