[mythtv-users] Frontend gui closing

[Jason Kitching]

Hi,

Upgraded from 0.27 to 0.28 (fixes/0.28 (v0.28.1-8-ge9be5e0)) without any 
issues, everything working fine, with one minor exception.

If I turn off my screen whilst the frontend is still running, the gui 
closes. htop still shows the frontend.real process running as normal. I 
ran it from a terminal and the last 2 lines in the terminal having 
turned off the screen are:

QXcbConnection: XCB error: 3 (BadWindow), sequence: 2114, resource id: 
0, major code: 15 (QueryTree), minor code: 0
QOpenGLContext::swapBuffers() called with non-exposed window, behavior 
is undefined

A brief search on the web gave me link 
https://forum.qt.io/topic/39364.rss - although a couple of years old, it 
seems possible it's a QT drawer issue.

I've since tried changed the Theme painter from Auto to QT, OpenGL1 and 
OpenGL2 and all settings still give the issue.

As a small test, I've also ran a couple of mpg and mkv files through a 
seperate player, but that doesn't create any issues.

I've also tried a couple of different themes and they all had the issue.

It's a slight niggle rather than a game changer, but any help would be 
welcomed.

Cheers.

Jason
