Yes, looks like is a duplicate of this one, although does not have specific reproduction steps. This one does. Also, it looks like they investigated 1.32.0-insider, while I am still seeing this in 1.32.1. Also, I can repro this in the latest insider build with only the Python extension and no settings changed whatsoever (see below). Finally, I must admit finding repro steps was a bit difficult. So I am not fully convinced this issue is fixed, as implied by .
I can not reproduce this. Can you attach a gif / video showing this can you repro this using python?
Sure, here's a GIF: !
I can not reproduce with node. please try reproducing with python if you F1 developer tools put a breakpoint what do you see as scrollTop, scrollHeight and renderHeight at the exact moment when the debug console scrolls unexpectedly?
I encountered exactly the same issue as
then you can also try to answer the quesionts i asked .

Get your hands dirty and do some debugging. Thanks
Breakpoint is hit twice per manual . After the first time manually entering , with the breakpoint hit at line 85: scrollTop = 0, scrollHeight = 19, renderHeight = 214 scrollTop = 0, scrollHeight = 480, renderHeight = 214 After the second time manually entering : scrollTop = 266, scrollHeight = 480, renderHeight = 214 scrollTop = 266, scrollHeight = 80, renderHeight = 214 (+) After (+), debug console is scrolled to top. I noticed that during (+), the debug console is empty, but not during any of the other breakpoint hits. I double-checked: is not a typo of , the above numbers are correct.
Yes, I too can replicate this issue on my Mac
Ok, thanks for help everybody. I can repro on my mac. Investigating...
After investigating and discussion with we figured out it is a dup of

I'm facing this since few months now. Any clue on how to avoid this issue? Please do not keep on closing this issue as it is real.
Check the insider release and see if it's fixed for you (it was for me). It seems the maintainers have chosen to leave this broken for everyone until their next major release next month which is unfortunate.

sorry that this is a pain. I am looking into it but can not reproduce. Can you provide exact steps please?
Hi OP here. I can still repro the bug in official 1.34.0, so this is certainly not fixed. However, my repro steps from the original description do not work any longer as running actually ends the process that is debugged. I managed to repro the same issue with . So these are my current repro steps: this code as in VS Code hitting the breakpoint, run in Debug console. a bunch of times (1-5 times) in the Debug console. that at one point, Debug console scrolls up quite a bit to bottom of Debug console output in Debug console. that you don't see due to Debug console scrolling near top again. Here's a gif as well. (The gif misses step 6, but I think it gets the main issue across.) !
Thanks for the steps, I will look into this this or next week.

we have pushed a fix with the help of Please try it with VSCode insiders starting from Tuesday which will have the fix. Thank you
I have just checked and it seems to me the issue is gone, thank you! (Of course, I will be more confident once an actual release has the fix as I haven't re-setup insiders the exact same way I use my release version - let's hope for the best!)
Thanks. Adding verified label. Let us know how it goes once you get the stable update.
Stable looks good to me, too, thanks!
