• Platform:
  Linux 6.13.6-200.fc41.x86_64 # 1 SMP PREEMPT_DYNAMIC Fri Mar 7 21:33:48 UTC 2025 x86_64 GNU/Linux
  Gnome desktop (both X11 and Wayland)

• MythTV version:
  fixes/35 (v35-Pre-802-gd620cc2ed9)

• Package version:

• Component:
  frontend

What steps will reproduce the bug?

Use LIRC remote during playback (MythTV, MythVideo, or MythMusic).

How often does it reproduce? Is there a required condition?

Always. Other users have reported the problem here: https://forum.mythtv.org/viewtopic.php?f=36&t=5863

What is the expected behaviour?

Remote buttons should work in player as they did in fixes/34.

What do you see instead?

Remote buttons do not have an effect. Remote works fine outside of player (eg. in main UI).

Additional information

Remote buttons work if this change is reverted: 794f53d
It looks like this caused the screensaver to appear to be asleep, which prevents remote events from being processed as per mythtv/libs/libmythui/devices/mythinputdevicehandler.cpp, line 263:

        MythMainWindow::ResetScreensaver();
        if (MythMainWindow::IsScreensaverAsleep())
            return;
        QCoreApplication::sendEvent(target, key.data());
