Apart from qt.qpa.xcb: internal error: void QXcbWindow::setNetWmStateOnUnmappedWindow() called on mapped window I didn't find anything useful, but the first attempt was the only one when the startup screen showed up. 😬

I think it might not be a SDL issue. My reasoning will sound weird but when you alt+tab to see opened windows you can see the preview of all opened applications. So before clicking restore or create a wallet I use alt+tab to see how the SDL window looks like. Sometimes it looks just as black, sometimes just as the picture above. So when I see the black window after alt+tab I can be sure that the startup window will have a GIF as it should be.

UPDATE: tested a few more times with removed .sdl folder and after compiling, looks like it works just fine. I don't know now. @duke

@onryo if you can no longer reproduce this, then I guess there is nothing to do. But my guess is that it only happens sometimes.

If you search for QXcbWindow::setNetWmStateOnUnmappedWindow() called on mapped window many projects have bugs related to this, such as:

https://github.com/mumble-voip/mumble/issues/3977#issuecomment-592658000

From that issue, it seems that whether the app is maximized or not matters for the bug (at least in their code) and also the behavior changed from QT 5.12 to QT 5.14. It looks like a QT bug.

@onryo what version of QT have you seen this behavior with? And do you notice any different with a maximized/non-maximized window?

It's HushBox, so 5.15.2.

@onryo what version of QT have you seen this behavior with?

I use the default non-maximized window.

And do you notice any different with a maximized/non-maximized window?

Looks like it, but I wouldn't be so sure though, good thing it happens only during creating a wallet, but not always. Today I could reproduce the problem only once out of ~10 attempts. I'll close the issue if I won't be able to see that in the next few days, or I will just report with more data, hopefully.

if you can no longer reproduce this, then I guess there is nothing to do

@onryo do you know what xcb options your QT was configured with?

From:

https://doc.qt.io/qt-5/linux-requirements.html

Note: From Qt 5.15 onwards, Qt does require libxcb 1.11. Also, the -qt-xcb configure option got removed that was bundling some of the libs below. Anyhow, you can now configure with -bundled-xcb-xinput to avoid a dependency to system xcb-xinput.

So this bug may change depending on whether -bundled-xcb-input is used to configure QT

Yes -bundled-xcb-xinput was used.
