Hello, I'm seeing a problem on my SDS2104X Plus scope where if I have the zoom enabled and perform a single trigger operation, I get spurious traces displayed. It looks like the signal is written twice to the display, once correctly and then again with a different time offset. If I change the horizontal time-base, change the offset slightly, or any operation that causes the screen to refresh, the correct waveform is displayed. I've done a quick search of this topic, but I don't see it mentioned. I'm running the 1.3.9R6 firmware, but looking at the release notes for newer firmware, they don't mention this issue being fixed in any newer firmware.
In the attached jpegs, capture5 shows the display with extra data that shouldn't be there, and capture6 shows the display after tweaking the horizontal position knob.
Is this a known issue with 1.3.9R6?
