https://bugs.winehq.org/show_bug.cgi?id=41909 --- Comment #6 from Nikolay Sivov <bunglehead(a)gmail.com> --- Ok, thanks. I checked out your trunk revision, and I think I see where this comes from, this dialog does: --- r->valueSlider.SetRange(-SliderResolution / 2, SliderResolution / 2); r->valueSlider.SetTicFreq(SliderResolution / 8); r->valueSlider.SetPageSize(SliderResolution / 8); --- According to my testing SetTicFreq() makes a difference, because it updates thumb position (TBM_SETTICFREQ does not have additional deferred update argument, so it always updates). We currently don't touch thumb at all on TBM_SETTICFREQ. Could you do a test build of your application without SetTicFreq and SetPageSize call to confirm that it breaks on windows too? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
