Description sunwebrw 2017-03-22 17:11:15 UTC
1. Open Blender
2. Click on slider and drag it left/right. In Blender almost all places that have numbers are sliders. For example, look at the bottom for "Start 1", "End 250".
3. In KDE under X and GNOME under Wayland you can easily change value big by sliding.
In KDE under Wayland slider isn't functional. At most you'll see a value changes by 1.

Blender is an X11 or a Wayland application?
Comment 2 Martin Flöser 2017-03-26 09:44:50 UTC
Which Xwayland version are you using? And are you using the same base system when testing with GNOME?
Comment 3 sunwebrw 2017-03-26 18:57:00 UTC
I have no idea whether Blender supports one or both. Their toolkit is written in python.
XWayland version xorg-server-xwayland 1.19.3-1.
I didn't use Gnome in the same distro. To test it in Gnome i've used latest Fedora's live image. I am using Manjaro and didn't want to screw up my system with Gnome which is community edition here. But i'll setup some system for testing soon enough

Same distro, Gnome under Wayland has fully working sliders, KDE - not.

Kwin 5.10.5

It works!
Comment 6 sunwebrw 2017-10-15 08:24:19 UTC
Ok, it sort of works. Almost fixed.
Sometimes you can drag slider right away and sometimes it doesn't and start sliding only after you move a mouse few times in different directions. Atleast there is some progress.

Sometimes it also says "pointer locked to current position" and that i need to press and hold Esc for 3 seconds to unlock it.
