Sliding channel #2 visualization bug

[voidexp]

Describe the bug
Channel 2 of the 6022BL scope seems not to catch the trigger (if I use the right terminology) and continuously slides from right to left.
Check out animation.

No problems on Channel 1. Tried switching probes, problem remains.

To Reproduce
Steps to reproduce the behavior:

1. Start OpenHantek6022
2. Attach the channel 2 probe to reference 2Vpp/1kHz signal.
3. See the sliding erratic behavior.

Expected behavior
The signal stays fixed in place.

Expected behavior
The signal stays fixed in place.

It would trigger on CH2 if you had selected this channel as the trigger source. However, your source is set to CH1:

This can also be seen from the colour of the trigger position slider at the top of the screen: It is yellow for CH1 and blue for CH2:

Oh... stupid me :) But wouldn't that leave the first channel floating then? What if I want to compare two signals at once?

If both channels are unrelated, only one channel can be fixed. If you want to see a steady picture, just use single trigger mode or stop the capturing with the pause button.
