Steps of reproduction

  1. Run Firefox-117.
  2. Open a page with lots of images and text, for example https://dymontiger.livejournal.com/19195316.html or https://mobile-review.com/all/articles/newphones/5-glavnyh-smartfonov-avgusta/
  3. Scroll down and up several times. Scrolling becomes laggy. The bad thing is that the bug can't be reproduced the first time. You need to scroll several times. And one more thing: scrolling does not need to be fast.

    Expected behavior

  4. Run Firefox-115.2 (or 116).
  5. Open a page with lots of images and text, for example https://dymontiger.livejournal.com/19195316.html or https://mobile-review.com/all/articles/newphones/5-glavnyh-smartfonov-avgusta/
  6. Scroll down and up several times. Scroll is smoothly.

    Current Behavior

    Scrolling becomes laggy

    Stack trace

    None

    OpenGL trace

    If necessary, I will do it.

Other details

With xfce-4.18 there is no problem. With backend= "xrender" - no lags. With backend = "egl" - same problem.

Correction: with backend= "xrender" - there are also lags.

Later I have been testing and searching for the problem for several hours using mozregression. Found a bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1836668 In the patch https://hg.mozilla.org/mozilla-central/rev/e1c387461f14 I saw a new variable: gfx.x11.glx_sgi_video_sync I changed it in about:config in Firefox to true - and everything started working as before.

Please tell me - is this a problem in Firefox or in Picom? But if in Firefox, then why is there no problem in xfce-4.18? Maybe there is some option in the picom settings that would correspond to this innovation in Firefox?
