In http://bugzilla.suse.com/show_bug.cgi?id=1140084, there is a report of a
VirtualBox guest constantly stealing focus from the host. I have
duplicated the
result with a fully-updated Tumbleweed with Qt 5.13, VirtualBox 6.0.8, and
a
Q4OS guest VM. When I booted into Leap 15.1 with Qt 5.9, but using the same
version of VB and the same VM, the behavior was normal. This suggests that
the
problem is with Qt 5.13. In https://bugreports.qt.io/browse/QTBUG-76742,
the
problem is listed as a Qt regression, and a workaround is suggested there;
however, a definite fix is not available.

I'm not sure who maintains Qt, but I would like that individual to contact
me.

Sure, what should we do? The QTBUG looks like it might be fixed soon, but we
can also add a # PATCH-FIX-OPENSUSE to change the timer to 200ms as that's
mostly harmless (but not a complete fix).

Fabian,

Thanks for contacting me. Could you please take ownership of bsc#1140084?

Done and a test package is building on OBS now.

If the QTBUG is fixed soon, then the only need is for the fix to get into TW
as
soon as possible.

I would like to test to see if that timer change actually fixes Tumbleweed.
Which package should I check out so that I can build and test? I am concerned
that the timer change is "mostly harmless". Would would it cause failures
elsewhere?

Any change in behaviour can potentially cause issues somewhere, especially if
the way the workaround was discovered was pure trial and error...

I did have a quick look at the VBox code now and the timer change seems
reasonable, so I think we can pick it for TW.

Cheers,
Fabian

Thanks,

Larry
