Description Paul DeStefano 2017-11-20 19:05:58 UTC
Description of problem:
After updating to firefox 57, XWayland freezes immediately when clicking the bookmark button to add a bookmark.  I can move the mouse, but I cannot move windows or switch focus (follow focus) and I cannot interact with any window, including FF.  This lasts for about 5-10 seconds.  Then, window service is restored, but FF is using more than 200% CPU (two processes >100%) for about 60 seconds.  I think this is firefox sync service.

Version-Release number of selected component (if applicable):

How reproducible:
Always since FF57

Steps to Reproduce:
1. F26
2. Setup firefox sync
3. upgrade firefox
4. make a new bookmark

Actual results:
XWayland temporarily freezes/hangs

Expected results:

Can you please attach a backtrace when firefxo freezes as per:


Comment 2 Paul DeStefano 2017-11-20 21:51:49 UTC
I'm not sure I can, actually.  It's not a crash; the freeze is only temporary, and it's all of XWayland, so I cannot force a crash with gdb as I cannot take any actions with the computer during the freeze.

But, I quit and restarted firefox, and now I don't see this behavior.  So, let me see how this goes for the rest of the week and I'll update this bug.

Comment 3 Paul DeStefano 2017-11-24 22:25:15 UTC
I haven't seen this since restarting firefox.  I don't know why that would be, but I think I'll close this bug.  I suppose I can always reopen it later if it recurs.
