threadedqopenglwidget sample causes an assert on resize

LudoJ49

Hi,

I'm trying to do an OpenGL app with rendering in a thread. So I look at QT sample "threadedqopenglwidget".

Everything is fine, until I resize the window. Then, I have an assert with "Cannot make QOpenGLContext current in a different thread".

Any idea of what causes that ?

Here is how to reproduce :

build the sample "threadedqopenglwidget"
resize the top level window (the one with only one QT logo). When I say resize, resize like crazy, lol
The assert should happend

Hi and welcome to devnet,

You should add what version of Qt/OS/Graphic card you are currently using.

QT5.5.1 on Windows X
Graphic card is Intel HD graphics4600

Do you mean Windows 10 ?

Did you check that one of the not threaded application work fine ?
