Expected behavior

Should Be Responsive As i type in any CLI Interface.

Actual behavior

When I complete typing my whole command and look at the screen it has started typing The first word.Sowly typing letter by letter.

I don't have any such problem on opening powershell from win + x But I love the design Of terminal,Therefore came here to report the issue.

By the way, Command Prompt(cmd.exe) is working absolutely fine but i am more comfortable with interface of windows powershell.

Please Fix this bug as soon as possible

I Dont Have any Recording Tool To Attach The Recording.So,sorry couldn't give proof

Summing up, The problem is only Windows Powershell is lagging a lot while typing in windows terminal.But runs Perfectly Fine While opened as Standalone(form win + x )

@Rasesh2005 -- can you please reply with the following information:

  • windows version (e.g. windows 10 -- patch 1803/1903/1909/2004 etc.)
  • graphics card (e.g. intel iris, nvidia gfx 960 etc etc) and the driver version
  • screen resolution (e.g. 4000 x 3000) and screen refresh rate (e.g. 60hz?)
  • laptop screen or external monitor? both? Does the lag happen on both screens or just external?
  • what version of windows powershell? Try running it as powershell.exe -noprofile does it still lag?

windows version -- 2004
amd radeon graphics chip(don't remember the exact model)
720p display
laptop

$psversiontable is as follows

Name Value

PSVersion 5.1.19041.1
PSEdition Desktop
PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...}
BuildVersion 10.0.19041.1
CLRVersion 4.0.30319.42000
WSManStackVersion 3.0
PSRemotingProtocolVersion 2.3
SerializationVersion 1.1.0.1

powershell.exe -noprofile doesnt make any diffference

But My concern is that it is working smoothly when launched from win+x or right clicking start button. But When Opened in terminal it lags a lot,like after typing the whole sentence, its still typing first word at the rate of one letter every 2 seconds

When launched from Win+X that's the original conhost which uses GDI+. Windows Terminal is something very different. It uses DirectX and DirectWrite technology. It also adds a lot of other fancy things. So it should be expected that Windows Terminal has different performance comparing to conhost. Of course we do not want the lagging. Just to point out the essential difference of those two fellows.

We'd also love to fix whatever problem you're experiencing. But you gotta give us more context. The CPU & GPU, memory, driver, all those things may help.

By the way have you tried software rendering? This may also help.

@Rasesh2005 Try what @skyline75489 mentions above -- there's a setting you can change that will use a different method to draw the screen. It may alleviate the problem by bypassing bugs in your video drivers.

Sure! You want to add it to the top-level of the json object, next to defaultProfile, like so:

@Rasesh2005 Is this a work computer? Do you have a corporate antivirus running? Or your own personal one?
