[solved] qt6 update 6.7.3-1 touchpad tapping always doubleclick

DE: lxqt
Device: logitech k400r keyboard with touchpad

Since full update 24/09/28 the touchpad of my logitech k400r keyboard suddenly always does double-clicks when tapping. I assume it has something to do with the latest qt6 6.7.2-3 => 6.7.3-1 updates:

Downgrading everything back to 24/09/27 and touchpad does only makes one click when tapping.
Updating to 24/09/30 (today) and setting whole qt6 group as ignored in pacman.conf: touchpad tab one click.

Does the problem appear again if you update back to the latest version? Just wondering because it sounds so strange

Definitively yes!

- removed qt6 from ignore in pacman.conf -> updated -> reboot: touchpad makes doubleclicks
- complete rollback via Arch Linux Archive to 24/09/27 -> update with qt6 group ignored -> reboot: touchpad makes normal one click

gromit · 2024-09-30 10:53:13

But are the qt6 packages the only ones being downgraded when you go back to 24/09/27? Could you send the full list (see /var/log/pacman.log)?

When updating coming from 2024-09-27 with qt6 group ignored the touchpad works normal (one tap - one click):

Works fine on Plasma, you may want to check with lxqt upstream.

I'm having a strange input issue with qt6 6.7.3 as well. I'm using KDE and in the desktop settings, I have configured the mouse scrollwheel to flip between virtual desktops. Since the qt6 6.7.3 upgrade, this has started to behave very erratically: often it gets ignored when I scroll, and sometimes it flips 2 or 3 desktops at a time, occasionally even in the opposite direction. I confirmed this on two separate computers, and with a fresh profile. Rolling back the qt6-* packages to 6.7.2 fixes it.

I can't prove that this is related to the issue the topic starter is having, but it is a weird coincidence at least.

vEnhance · 2024-09-30 21:59:21

I'm also suddenly having mouse input issues with qt6 @ 6.7.3 on two separate computers that is resolved by downgrading all qt6 packages down to 6.7.2.

My symptoms appear a little different since I'm on a desktop rather than a laptop. I have a left-handed mouse, configured by setting

xmodmap -e "pointer = 3 2 1"

; however with qt6 @ 6.7.3 the following symptoms occur:

In qutebrowser this causes both mouse buttons to be secondary clicks. However, if I go back to using a normal right-handed mouse, the two mouse buttons function as expected (for a right-handed person).
telegram-desktop has the same behavior as qutebrowser.
Meanwhile, in some other qt apps like shotcut and obs-studio-tytan652, the behavior is a more erratic. Don't have a good description but also not working as expected.
Non-qt apps function normally (as detected by
```
pactree -r qt6-base
```
) work fine.

Here's the pacman log of the downgrade that fixes the issue for me; I manually specified the qt6 packages in `/var/cache/pacman/pkg` rather than using a downgrade tool.

Possibly of note, I have a nonstandard `ffmpeg` (I'm on `ffmpeg-obs` because I'm stuck with it for `obs-studio-tytan652`).

And also can't prove the issue is related to either of the two above, but seems similar enough I thought I'd report in case it's helpful. Seems like it might not just be coincidential.

It is indeed related. I also downgraded "python-pyqt6", which is of note as it does not follow the same version numbering - it needs to be downgraded to 6.7.1-1.

The qt developers will fix it soon one way or the other. From what I can tell, the commit that caused this bug was to fix clicks not registering while the super key is held down - so now, instead, clicks often register twice, or register once when they should be redirected by a modifier key.

There now has been a revert added, so please re-test if that also fixes your issues! @renegat @mesaprotector

Seems to work fine for me now. I tested featherpad, nomacs, and audacious. Thank you very much.

renegat · 2024-10-02 08:25:52

I can confirm the issue is solved with qt6 6.7.3-2 updates.
No more unwanted double-clicks from logitech k400r touchpad taps.

vEnhance · 2024-10-03 13:11:43

My issue is also resolved by the update to qt6-base.
