Comment (by hamelg):

I use the mythbuntu theme.

I applied the workaround suggested here to remove the white rectangle :
https://forum.mythtv.org/viewtopic.php?f=36&t=3505#p16947

In the file Mythbuntu/base.xml :


{{{
<webbrowser name="basewebbrowser">
<area>0,0,0,0</area>
</webbrowser>
}}}

Comment (by thebitpit):

Bug https://code.mythtv.org/trac/ticket/13566 is a duplicate of this bug.

The actual problem is caused by the creation of an unused child webbrowser
window at startup that is never destroyed. The white window is the unused
browser window. The display order gets changed so that appears to come and
go. It is not on top some of the time. The workaround makes it so small it
doesn't get in the way.

Both mythfrontend and mythtv-setup have this bug. I suspect it has been in
mythtv for some time. The latest Qt version exposed it by changing the
order of visibility.

By the way, editing /usr/share/mythtv/themes/default-wide/base.xml in the
gentoo distribution should workabound the problem for wide themes.

Comment (by Peter Bennett):

Is this caused by one of the plugins? Check by testing without plugins
installed.

paul-h,
Good work with patch. I tested this on Qt5.14.1 on x86_64 and aarch64.
Works perfectly!
