Black bar instead of title bar on Intel Graphics when you have a QOpenGLWidget

[vtronko]

Black rectangle is just 50x50 QOpenGLWidget.

What's more interesting, hitboxes are correct (it means it receives clicks exactly where it should) while painting is done with offset.

It's related to https://bugreports.qt.io/browse/QTBUG-40485?page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel&showAll=true

Is there any adhoc solution to workaround this?

There's an answer in closed #19 thread but it's not clear.

I've been suffering from this as well. Any luck on your end on finding a solution @vtronko?

I've noticed resizing the window after this issue occurs fixes the offset. So I've been trying to figure out if I can trigger a windows event that forces a repaint or something.

What is very odd is I only see this if I move my app across monitors with the same level of text scaling. If they don't have the same level of text scaling, the offset does not occur.

@JosephCoppola-FW no, I just implemented a fallback version for unsupported chipsets -_- Wasted too much time on this one

Yeah this one is killing us a bit.
