Strange flickering in the waveform display #11340
Comments
Which of the possible waveform types is affected? |
Probably it happens when tracks are quickly and randomly loaded and unloaded after each other to the two decks. It happens with all the GL and GLSL types except for the new “RGB (QOpenGL) (GLSL) “ type. On this video that I recorded for reporting another bug, you can see it suddenly appearing at ~13 sec: System info:

I also have this issue (that flickering in all GL/GLSL waveforms like in the 2nd video) with recent 2.4 branch (9df9dcb), so I blamed this version for this and went back to the last working commit I was aware it had worked before. Unfortunately the issue was still there, so I did some further investigation yesterday. |
Additionally I also experienced this problem with 2.3.3-121-gd1f63374fc. |
I am surprised you are seeing this waveform type. This type was added in pull request, #10989 , which as far as I am aware has not been merged into the main branch yet. (Apart from the added waveform type it used a different backend for all GL widgets) |
For testing I additionally built a code that includes #10989 ;) |
That explains things! Flickering aside, do you notice improved performance, especially when using this new waveform type? Running at 60 fps smoothly?

@m0dB in my experience it behaves just as smoothly and jerky as before. It runs quite smoothly, but jerks when the mouse goes above it. I created a video, it captures well its performance and jerking. Set the youtube playback to 1080p60. 0:01 RGB (GLSL) |
This problem seems to be gone in v2.3.5. |
Bug Description
With main I observed some strange flickering in the upper waveform display region. I still don't know how to reproduce it because it is really intermittent. It looks like this:
