0.99.1: Scroll Speed Fast

Post by Akovia »

XnView MP Linux
Version 0.99.1 64bits (Sep 23 2021)

After last update, the mouse scrolling speed is insanely fast.

Effect: Scrolling is just unusable anymore. My Logitech M705 even has a button to enable an indent in the scroll so you can easily increment without over scrolling and even with this enabled it scrolls at least 3 pages. I'm not seeing these issues in other programs.

I've tried power cycling the mouse and moving the receiver to different USB ports, but neither had an effect. I also tried a wired mouse (Mx518), but even thought it's a bit slower than the 705, it still skips images when cycling in fullscreen. This mouse uses a detent all the time and normally would increment one image at a time.

To reproduce:
Scroll anywhere in XnViewMP

Actual behaviour (bug): Scrolls too fast

Expected behaviour: same scroll speed as previous version

I found some information that might be useful.

It would be great if you could have a look. The program is almost unusable for me as it is. I've had to resort to grabbing the scroll bars which has really slowed me down.

Thanks!

I can't really tell a difference other than in XnViewMP and one browser extension. (Imagus)
I can take a video if you like to see the difference, but browser scrolling works fine.

If there are other programs with the issue I haven't found them yet.

I went ahead and made a video.

https://mega.nz/file/AAoQWQza#JqiJW5kAd ... YPHDG0K7uA

What I found is that the extreme fast scrolling happens in the browsing window and not in the file folder window on the left.
I am using a Logitech M705 mouse and it has a button to enable scrolling with a detent to scroll one item at a time. Even with this button it scrolls 4+ images at a time. With it turned off which is how I normally use it, it's even worse.

You should be able to see in the video when I'm scrolling the images maximized, that the number of images that scroll by in a single scroll is usually 4, but sometimes more. This is in the notched mode. In free scroll mode it's hard to control it at all. But when scrolling the file folders on the side, it works like it always has.

Please let me know if you need more information.

Version 0.99.1 64bits (Sep 23 2021)

I've actually had to downgrade xf86-input-libinput because I just couldn't work with it the way it was. There were more programs than just XnViewMP that had the problem as well. (My Imagus Chrome extension, and SMPlayer)

They are proposing an option to disable high resolution scrolling in xorg.conf, but that is just a workaround when programs aren't supporting it properly. You can follow that progress here and possibly get some information about supporting high resolution scrolling here.

If I can be of any help to troubleshoot, I will certainly do what I can.
Thanks as always!

EDIT: I do have an extra M705 mouse if you'd like it for testing. Not sure where you are located, but I'd send it if it wasn't too expensive to ship.
