What's Wrong?

When the task tool is working, the screen flickers constantly as if the content buffer is scrolling to the top and then back to the bottom over and over again. This is similar to a bug I report previously but in this case, the issue only happens while the task tool is active.

What Should Happen?

the claude code screen should stay displaying the bottom of the content buffer or whereever the scroll position is set to

This can also be mitigated by having an command/ mode (similar to ctrl+o for output) which will collapse all task outputs under the task bullet

@softwarecatscomgm can you elaborate how to do this?

This is how it works today

o Task description
   Lots of task commands and output
   Lines and lines of task activities
   Each time this area is added to the screen redraws

This is how it could work:

> Task description

Press ctrl-1 (for the first task), ctrl-2 for the 2nd task or ctrl-+1, ctrl-+2, etc.

v Task description
   Lots of task commands and output
   Lines and lines of task activities

The task can be expanded in place or displayed on an alternate screen similar to ctrl-o

happens on wsl2 only during task tool usage, constant refreshing of the buffer causing screen flicker
