Hi. I have a 4K monitor and my volume and pan sliders jump only between zero and all down. It stays all down and you cannot move it up. same with pan. It goes to a side and stays there. If you klick on it, it jumps to zero. This is really frustrating. And is the same in x3 and platinum. I need the screen to have 2160p because of video projects. The strange thing is that the knobs work after a minute of jumping between 0 and all down. Is there a fix coming for this bug? I can document it in video if you need that.

I would document it here then see if other with 4K screen can replicate it.

I do not have a 4K screen but problems start on any system when the screen display is significantly different than 100%. I can get away with 125% with just a few display problems but knobs and faders work OK. This is feature request territory. Similar threads:

yeah the screen is at 150%. ill try to change it to 125%.

i guess this is for screen setting over 150%

Does this mean adjusting the display makes the problem go away?

That's right. Sonar has a bug with 150% in 2160p
If you adjust your screen resolution to be 1440p or going back to 125% the problem is gone. 125 is of course to small to read labels and so on. So only workaround is to downgrade the resolution to 1440p

It has nothing to do with 2160p. AFAIK SONAR does not support running any display higher than 100%. Even at 125% there are minor display issues.

That jumpiness is the same FM and I experience in this thread

Anyone with a bigger understanding know how this could be related when I'm viewing at 100%

For whatever the worth, I had some display issues in prior releases, when I had adjusted my screen resolution to 150%, and all of those issues went away when I put it back to 100%.
