User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:56.0) Gecko/20100101 Firefox/56.0
Build ID: 20170630100234

Steps to reproduce:

Open a Tab in Nightly (Build-ID per Tester Tools:
Mozilla/5.0 (X11; Linux x86_64; rv:56.0) Gecko/20100101 Firefox/56.0 ID:20170630100234 CSet: d9a144b7b6d994fc9a497c53b13f51a2a654d85e)

Enable or disable the kwin compositor (Shift+Alt+F12)

Bug still happens when starting with safe-mode.


Actual results:

All current tabs become blank. The websites seemingly still work in the background as sounds are still played and the youtube autoplay feature still works.

The following message is shown on the CLI when closing a blanked out tab:

IPDL protocol error: Handler returned error code!

###!!! [Parent][DispatchAsyncMessage] Error: PLayerTransaction::Msg_ReleaseLayer Processing error: message was deserialized, but the handler returned false (indicating failure)


Expected results:

Nothing

I can confirm this issue on current nightly running on Mageia 6 x86_64 under Plasma 5.8.7 and GTK+ 3.22.16.

Another manifestation of this issue (which is why I landed here, looking for an already filed bug for this annoying behaviour) is to start any kind of fullscreen native game (e.g. 0 A.D.) with Nightly running in the background. All tabs are blanked and show the "loading" spinning icon. Reloading the tabs does not help, one needs to restart Nightly to see things again.

That's because KDE disables the compositor automatically when any kind of fullscreen application is launched.
Seems to be fixed. Don't know which version exactly fixed it, but the bug does not appear in the 2017-08-17 build.

Hi there! Could you please confirm whether this bug is fixed on the latest Beta 56 [1] as well? I'd really appreciate it!
