User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0 Build ID: 20170302120751 Steps to reproduce: Used Firefox for general internet browsing. Actual results: During general use of Firefox on my Dell XPS 13 (QHD screen with touch) there is noticeable extremely frequent frame drops on all websites even on very basic websites like facebook/reddit. This issue is also present on my friends laptop (a 4k asus w/ touchscreen). Expected results: Frame rate should have stayed above 60fps/30fps at the least. NOTE: when plugging my XPS into a 1080p monitor (and laptop screen is off) firefox does not lag, on my laptop the scaling is at 250% but on the monitor it is at 100%
I should also add it makes firefox almost unusable at times.
Hi teccenter23, I have tested this on windows 10 with the latest nightly on a 4K monitor, but could not manage to reproduce. I did not test it on touch enabled screen though. Could you please use the steps mentioned in the above link(comment 2) to submit a profile? Thanks
Closing this as incomplete due to inactivity and lack of response from the reporter. If anyone can still reproduce it on latest versions, feel free to reopen the bug and provide more information. Thanks
