[gwenview] [Bug 388353] Scrolling with the touchpad is too fast
https://bugs.kde.org/show_bug.cgi?id=388353 --- Comment #16 from Nate Graham --- You may be thinking of https://bugreports.qt.io/browse/QTBUG-59261, which is not the cause for two reasons: - It only affected the libinput driver, but RaitaroH is using the Synaptics driver - The bug caused touchpad scrolling with libinput to be too slow, not too fast Or maybe you're thinking of another Qt bug that I'm not as familiar with? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=388353 --- Comment #15 from Henrik Fehlauer --- Why is it not a Qt issue? Maybe I'm mixing up things, but wasn't there a problem where a newer Qt would send a gazillion of wheel events? Did someone actually test with a really old distro with an old Qt whether the problem is also present there? -- You are receiving this mail because: You are watching all bug changes.
[gwenview] [Bug 388353] Scrolling with the touchpad is too fast
https://bugs.kde.org/show_bug.cgi?id=388353 --- Comment #14 from Nate Graham --- Yes, seriously: - It's not a Plasma issue since Plasma doesn't affect apps' scrolling implementations - It's not an issue with the Qt scrollview since the problem described in this bug pertains to a custom scrolling implementation - It's not a driver issue (e.g. with synaptics or libinput) issue because it doesn't affect everything, just certain custom scrolling implementations like this one That leaves individual apps as the culprits. It's not at all a surprise to me that scrolling with a touchpad is still a second-class citizen in Linux software. Linux (and Windows, to be fair) folks have been relatively slow to adopt laptops with touchpads as full-time work machines without plugging in external mice, probably due to historically abominable touchpad input drivers and software support. We've already fixed Gwenview to handle touchpad scrolling more reasonably in other contexts; see for example Bug 378584. That was a pretty small patch; would you like to have a go at producing a patch based on that for this issue?

I thing at that point it might be something that could be fixed that would fix all of them at the same time. Also this is most likely not a full list either so that means even more bugs for the same thing. -- You are receiving this mail because: You are watching all bug changes.

If it were just a gwenview thing like I thought at first... why was: 1. latte affected (then had to be fixed) 2. switching desktops with scrolling over the empty desktop also affecred. The touchpad is too fast (actually I had no idea that was a feature before I discovered it by accident) 3. vlc is also affected when scrolling to increase or decrease the volume, which is really fast if done with the touchpad, but is ok if is with the mouse. I don't do it that much so I didn't notice. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=388353 --- Comment #8 from RaitaroH --- I first thought this is a Gwenview issue. I also noticed though that trying to switch desktops by scrolling with the touchpad (hover the desktop) is also very fast in imprecise. I even noticed that Latte-Dock had the exact same problem but it got fixed: https://github.com/psifidotos/Latte-Dock/issues/892#issuecomment-370139533 I think maybe this bug should be placed in another category and not gwenview. -- You are receiving this mail because: You are watching all bug changes.

For me and my touchpad settings it's not "100-images-at-a-time-too-fast", but still noticeably "too fast". We will probably have to apply another fix like the one in Bug 378584, just like Henrik says. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=388353 --- Comment #3 from RaitaroH --- @Henrik Fehlauer I already have it set to browse. It was the first change I made. Setting it to scroll and scrolling with the touchpad in a zoomed in image seems fine too me. It doesn't scroll too fast, but it is quite smooth (good thing). The mouse is more blocky, x number of lines with every small scroll. So there isn't any problem there from what you can see. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=388353 Henrik Fehlauer changed: What|Removed |Added CC||rk...@lab12.net --- Comment #2 from Henrik Fehlauer --- Thanks for the report. I don't have access to a touchpad right now so cannot reproduce, but at least I want to mention that beforehand you'd have to go to Gwenview's settings → Image View → Mouse wheel behaviour and select "Browse". I suspect the touchpad is creating a lot of very small scroll increments and this needs special handling in the code compared to the "traditional" way of scrolling (could probably copied from elsewhere, e.g. the fix for Bug 378584). (Regarding scrolling in QML based UIs like the "Add widgets" dialog: I believe this is a known problem depending on library versions and input stack. Unrelated to Gwenview, though.) @RaitaroH: One more thing: Could you also test whether scrolling (i.e. panning after zooming in in View mode) is also too fast when selecting "Scroll" instead of "Browse" in the settings? (And possibly anywhere else?) Thanks! -- You are receiving this mail because: You are watching all bug changes.
