[Bug 1173320] New: Ship with MOZ_USE_XINPUT2=1 set in the environment to improve Firefox touchpad & touchscreen scrolling
http://bugzilla.opensuse.org/show_bug.cgi?id=1173320 Bug ID: 1173320 Summary: Ship with MOZ_USE_XINPUT2=1 set in the environment to improve Firefox touchpad & touchscreen scrolling Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Other Assignee: screening-team-bugs@suse.de Reporter: pointedstick@zoho.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- On X11, with MOZ_USE_XINPUT2=1 set in the environment Firefox exhibits much improved pixel-by-pixel touchpad scrolling, and touchscreen scrolling actually works. On Wayland, the behavior is already enabled by default so the environment variable has no effect. Historically, the reason why this was not set by default on X11 was an outstanding bug that caused scrolling with wheel mice to periodically break: https://bugzilla.mozilla.org/show_bug.cgi?id=1182700 However this bug appears to only affect KDE Plasma systems, and the KWin developers just fixed an issue in KWin, and now the problem no longer manifests. See https://bugs.kde.org/show_bug.cgi?id=394772. Therefore, there no longer appear to be any blockers to enabling this behavior by default by setting MOZ_USE_XINPUT2=1 in the environment. X11 Firefox users should really appreciate this change. -- You are receiving this mail because: You are on the CC list for the bug.

Also FF78 will eventually land on Leap. Therefore we either need to unship that env or make it depending on some version check on a package? -- You are receiving this mail because: You are on the CC list for the bug.

I thought you'd already shipped Plasma 5.19.3 in TW, sorry. Yes, it will need to be reverted or made conditional on having at least Plasma 5.19.3. I suppose this won't be necessary for TW soon enough, but yeah, if the change would eventually be landed in Leap, it will be needed. -- You are receiving this mail because: You are on the CC list for the bug.

I already had this: if [ "$ID" = "opensuse-tumbleweed" ]; then export MOZ_USE_XINPUT2=1 fi to avoid it being used in Leap. -- You are receiving this mail because: You are on the CC list for the bug.
