Some visual elements like playback bar and Oscilloscope freeze sometimes

[SalutanisOrkonus]

Bug Summary

Sometimes seemingly either randomly or maybe after a bit of unuse, some relatively important things visually stop updating, like the playback bar (the gradient that shows up when you play still appears and disappears though), and less importantly things like the master oscilloscope. One time I had this happen I managed to fix it somehow but I don't know/remember how, so generally this forces a program restart. They still work functionally, but they don't visually change at all, which makes them useless. You can still interact with most actual elements in the song editor when this happens, I think.

Steps to reproduce

As completely unhelpful this really is, I have no idea. The latest time it happened was when I closed my laptop with LMMS still open, and got back to a while later and it happened. Idk if that's helpful or not, im not sure if the other time it happened even was under the same circumstances

Expected behavior

Everything will work properly when I press play/spacebar

Actual behavior

Some stuff is completely frozen even if I tri messing with it manually (enabling/disabling osc, ect.).

doesn't really work here

Affected LMMS versions

I'm on 1.3.0-alpha.1.506+gabe2c92be

Hi,

Not sure I clearly understand what you are talking about. I never observed any issue on the master oscilloscope but that’s clearly not a thing I look at often. What I noticed is widget not redrawn and instead showing the graphic content that was under them at a moment. Sometime I can see some graphics from the song editor drawn on an instrument, and it stays like this even if I move the instrument widget or move one of its a knob. This is not of a great level of annoyance, and the widget always ends being correctly redrawn, but it can destabilize a bit sometime.

managed to get a video recording of it happening to the playback bar song is clearly playing, but the bar is stuck at the start. you can also see the oscilloscope not moving.
