When i use firefox, after a while, any key typing (not mouse moving or clicking) gets delayed by 20 seconds or more. No other running program is affected meanwhile (e.g. thunderbird, shell window). The issue can only be fixed by restarting firefox Reproducible: Always Steps to Reproduce: 1. start firefox 2. use it for some time, usually longer than 10 minutes Actual Results: For typing, firefox is hardly usable anymore e.g. while reporting a bug in this bugzilla Expected Results: firefox remains usable firefox-114.0.2-1.fc38.x86_64
Additional info: firefox' CPU utilization looks normal while the problem is visible. So it should not be busy i guess. Pasting text with the middle mouse button works normally as well. Just typing does not.
Can you please run on terminal with MOZ_LOG="Widget:5" env variable like: MOZ_LOG="Widget:5" firefox 2>&1 | grep Key and check if key events are logged in time or are delayed? Thanks.
Cannot reproduce it currently. I have wrapped the firefox program, so i always get key events logged, when firefox is started. Please feel free to close this issue for now. When it comes back, i'll reopen.
Okay, Thanks.
