Hello Anidel,
I tried the new version. Unfortunately it is broken. When you first start it, it seems to be OK but after a few lines what you write does not appear to be where you wrote it but appears one or two lines above. Also the pressure sensitivity seems erratic and does not change linearly with the pressure. Maybe we should abandon the pressure sensitivity. Thank you.
What I see is that when I start the program (btw there is an icon now) the width of the lines is thick as without pressure sensitivity, and if I apply very very weak pressure it is still the same. If I go to option menu and I check pressure sensitivity then the lines appear much weaker but they are the same if I apply a lot of pressure, so where is the pressure sensitivity? The are only too values, strong if unchecked and weak if checked. If I uncheck xinput it reverts to previous behavior and the scrolling problem is not there also.

The icon shows up to you ?
I mean the icon on the left area, not in the menu... is that one that appears to you ?
About the width of the line, you're right.
I put the pressure on by default but it was barely noticeable with the default MEDIUM thickness, so I put that to the biggest value.
I think I will leave the default settings as usual and try to put a button easily reachable for it.
UI improvements are a must, now.
Unchecking Xinput makes Xournal behave EXACTLY as the former release.
Pressure sensitivity is a value between 0 and 1.
When it is unchecked the default static value for it is 1 (i.e. maximum pressure according to Xournal standards).
When you check it, then the value depends on the actual pressure.
On my tests it goes around 0.3 with the "regular" pressure and goes up to 0.4-0.5 when heavily pressed (using stylus).
If I use my thumb, tho, the pressure sensitivity values change drastically.
They go from a low value of 0.5 up to 0.9!
That's why with pressure enabled, the line is thinner.
Try to enable pressure and use your thumb to draw and apply different pressures while drawing a stroke.
That's why I've enabled thickness at its maximum, but this was for testing.
Anidel,
1. About the icon: There is no proper icon on the left (just the default 4 leaves). There is an icon in the application menu.
2. You are right that with the thumb pressure dependence is more visible.
Maybe mathematically you can stretch the range 0.3-0.5 to 0.1 to 0.9 or something like that? Like y=4 x -1.1 maps one interval to the other.
One more thing: I think the default should be Xinput unchecked, and people
who want preasure sensitivity can check Xinput and also check pressure sensitivity.
Thus we need a 'calligraphic input' button (maybe with a stylus pen icon) which toggles between pressure sensitivity plus maximum line width - and no pressure sensitivity plus the line width you choose in your tools menu.
Also, when shape recognitions intervenes, lines get the width set in the menu. So it could be nice to be able to separately choose the width of shape lines, so that you could simultaneously scribble text in calligraphy, with pressure sensitivity, and draw lines and circles with thin lines.
