Yeah, the compiler assumes that no floating point number is NaN or inf, so it
can make optimizations like: `x == x` -> `true`, `x * 1` -> `x`, etc. But I
think functions like `isnan` or `isinf` will sti

Awesome! :) I think QScroller shouldn’t break because of floating point
inaccuracy. But its complicated floating point calculations make it seem
possible to me.
What does -ffinite-math-only mean? That stuff like qNa

--- Comment #26 from abulhair.sapa...@gmail.com ---
I found the bug, for me, was being caused by compiling qtcore with the flag
-ffinite-math-only. I had previously ruled out optimization flags as being the
cause since I had recompiled okular and qtwidge

Actually I think I may have inadvertently fixed my issue. I tried recompiling
all of qtcore, qtwidgets, and okular with debug symbols as well as disabling
all optimization and now it's scrolling correct

Apparently parttest seems to have been excluded by Gentoo
(https://bugs.gentoo.org/641728), along with mainshelltest, chmgeneratortest,
parttest, and annotationtoolbartest.
Sure I'll try running okular

--- Comment #20 from David Hurka ---
Thanks! No fails related to QScroller visible. But what’s with “parttest”?
ctest didn’t run it, or cmake didn’t compile it?
Maybe we can try to look at internal values of QScroller. You will need to

No xD It happens on both of my Plasma systems: one is a laptop with a single
monitor, and the other is a desktop connected to a Denon receiver via HDMI (so
Plasma thinks it's a second monitor).

I have "show scrollbars" enabled in the Okular config window. I tried
experimenting with "Use smooth scrolling" but the behavior is the same. I am
able to scroll using the scrollbars. Interestingly, the
