Strange Glitches on Spike with BB06C

There is something strange happening when I am using Spike.
When I am running a wide span on Real Time mode, there are bands that appear across the top of the chart & clears all hold traces.

Attached screenshot.

Any info on this issue?

c3dr,

What kind of PC are you running the unit on? I’ve seen this type of behavior before on a low power laptop. Usually indicative of the PC not able to keep up with the processing and creating erroneous results like this. For the real-time spectrum analyzer modes we recommend quad core i5/i7 processors to keep up with the processing requirements.

I look forward to your response.

Regards,

i7-7700 desktop with 8gb ram & ssd.
Its more than plenty.

Powered directly through USB on motherboard.

Also was happening on older version of Spike, updated to latest, same.

Will you try something for me? It looks like you have a high resolution monitor? Maybe a 3K/4K monitor? Does it help if you try this same test after changing your PC resolution to 1080p? (or any resolution below 1080p)

Regards

It seems to happen when my mouse is moving over the graph display,

My monitors are a bit strange, 2 x 2k displays vertically, setting them both to 720×1280 made no difference.

What does the CPU usage look like when real-time is running? Is there an increase/jump in cpu usage when you move your mouse across the screen?

Are you running your monitors off the integrated GPU or do you have a dedicated GPU?

If you have time and the ability, I would be interested if it helps to run just a single monitor setup with a ~1080p resolution. I’m ultimately curious if it is related to your specific video setup. I can’t reproduce any issues here on a i7-6700 running 2 1080p displays.

Do you have any anti-virus software running other than windows defender? If you have any other heavyweight software running it might be interesting to see if closing it out helps any. This might be a long shot, but setting the PC to the high performance power plan might help, go to the “power options” menu in the control panel and set your power plan to “high performance”.

Regards,

CPU usage runs around 40-50% with the mouse moving / otherwise ~20%.

Integrated, ~20% GPU load dedicated to SPIKE. ~20% for Windows DWM.

I will try to single monitor later.

No Anti-virus at all.

But from these hints I can see it is heavily related to when I am mousing over the chart. Is there a way to disable the live update of the values in the bottom bar or anything related with simply mousing over the graph?

Thanks for your assistance.
