Could you please open the app directly through the cmd and send us the logs from there?

[gluons]

@SamvelRaja Not work 😟

[SamvelRaja]

@gluons you would have got some logs in your cmd. could you please get that for us?

[gluons]

@SamvelRaja Did you mean View -> Toggle Dev Tools? It's empty. I've no idea. 😟

[SamvelRaja]

@gluons Sorry to bug you again and again. we are just asking the command prompt screen shot.
I would like you to launch the app through your command prompt and need to give the logs appears on the command prompt. Like this

[SamvelRaja]

@gluons thank you so much.. We will look into it and get back to you in some time.

[SamvelRaja]

Hey, @gluons we tried reproducing the same from our end and it is working properly, could you please open dev-tools on the blank window and give us the value of window.location.pathname ?

[gluons]

[SamvelRaja]

@gluons could you please uninstall the app and delete the c:\Users\<User>\AppData\Local\Postman folder.
Then, download and install the latest 4.6.1 version.
Also, kindly let us know if you face any problem while installing which would be much helpful for us to debug.

[gluons]

I've uninstalled and deleted c:\Users\<User>\AppData\Local\Postman before reinstall new but still not work. still blank 😟

I've tried on other laptop with Windows 10. It not work too.

[SamvelRaja]

@gluons Thank you so much for your patience,
Seems like a process environment issue. can you make sure your NODE_ENV is not development system wise
you can find it under System properties -> Advanced -> Environment Variables

[Jeff-Lewis]

Removing NODE_ENV=development works. Are you guys going to remove this dependency in the distributed app?

In the meantime, for those that keep NODE_ENV=development set on their machines, you can update your shortcut to Postman to clear NODE_ENV just when Postman runs.

cmd.exe /c "set NODE_ENV= & C:\Users\<your win account>\AppData\Local\Postman\Update.exe --processStart Postman.exe"

[numaanashraf]

@Jeff-Lewis Yup. We are removing this dependency on NODE_ENV in version 4.6.2 which should be available within a day or two.

[SamvelRaja]

@Jeff-Lewis @gluons we released our 4.6.2 version which had the fix for removing the process.env.NODE_ENV dependency.
Kindly make sure this from your end.

[gluons]

@SamvelRaja OK, It work!

I'm using NODE_ENV as dev. I can't remove it. You save me. Thank you very much. 😃

[SamvelRaja]

@gluons Thank you so much for your patience while debugging the root cause 👍

[Arijit1234]

Hi ,
I just installed postman last week. It was working when I installed but stopped working from second day. The post will load the UI when I start it but within 2 min, it turn into a white screen. I am using Windows 10, i7, 16 GB ram.

regards,
Arijit

[KevinvdBurg]

I still got a whitescreen on the native app. The chrome app is fine. I'm using Windows 10 (fall creators update), Intel Core i7-2760QM 2.40GHz. 16gb ram, 64bit.

Native:

Chrome:

[SamvelRaja]

@KevinvdBurg By any chance, you are running ia32bit version on your 64bit OS?

[nkpaladugu]

I have same issue on windows 7 32 bit, installed postman v5.3.2.. On opening, its just turned into a white screen.

[KevinvdBurg]

@SamvelRaja no I downloaded the 64bit version

[KevinvdBurg]

Almost a month has past and this issue is still not fixed. I had contact with the support team but it keeps telling to starts postman from the Command Line (what I did).

What I found is that if I click and drag on the postman screen it exactly drags something. No clue what this means.

[razikallayi]

Same blank screen issue for me too.
Postman version: 5.5.2
Windows 10 64bit Os

The problem is with windows app. I have tried reinstalling the windows app.
But chrome app is working almost fine with the deprecation message and with reduced features.

[KevinvdBurg]

I can confirm that the app still shows a blank screen. The issue at the postman issue tracker is therefore still open.

[erdemkose]

I also had the same issue with the native windows app.

My laptop has two graphics cards:

• nVidia Quadro 2000M (Default)
• Intel HD Graphics

When I switch to Intel, Postman works; otherwise it is just a blank window.

[davutg]

Postman is an indispensable tool for me, but I'm in trouble with updates.
This occured for me again after another update today.I'll think twice for further updates. I previously migrated from Chrome extension edition and it was also hard for me. This time I just clicked update and lost it again.

Windows 8.1 64 bit,
Downloaded the latest version, 6.1.2
Updated shortcut's "Start In" directory manually because it was searching for 4.x previous version.

Black/Gray or White screen appears , many postman.exe processes seen in task manager and i7 CPU had some hard time without a result. For further updates I'll consider re-installation instead of update.

[teebu]

just updated postman, Windows 8.1, 64 bit. the standalone version.

Blank screen. I can somewhat interact with the menus.

The Chrome App works.

[orck-adrouin]

I has the same issue as @teebu on Windows 2012r2 64 bits. I was able to work around the issue by setting compatibility mode on postman.exe to Windows7.

[dmarkowicz96]

Same problem here. 'Troubleshoot compatibility' has resolved issue. (Windows 8.1 PRO)

[samizzo]

I'm seeing this too. This is all I see in my console when I start postman:

C:\Users\izzo\AppData\Local\Postman\app-6.1.3>
ORM initialization successful
App events bus { name: 'booted', namespace: 'shared' }
App updater event { name: 'checkForElectronVersionUpdated',
  namespace: 'appUpdate' }
App events bus { name: 'booted', namespace: 'requester' }

[eMarv]

@dmarkowicz96 's solution worked. Thanks! I am also on the same version of Windows.

For those who don't know, you can do this by:

1. Finding your Postman.exe file, which for me was in C:\Users<username>\AppData\Local\Postman\app-6.1.3
   a. replace with your actual username
2. Right click on Postman.exe
3. Click on Troubleshoot Compatitility
4. Follow the instructions in the prompts

[oomaks]

I'm developing an electron app and have the same 'blank screen' problem as Postman 6.13. Have any one know why this happens. Why @dmarkowicz96 and @erdemkose 's solution works?

[iamthevoid]

@eMarv A lot of thanks and lot of love !!! )) You saved my day

[eatinasandwich]

Was having this issue on Windows Server 2012 R2. Troubleshoot compatiblity worked for me too but I had to do it a second time this morning for some reason. Would be nice to have a better fix for this so it doesn't randomly occur.

[DaDude]

My guess is it's related to old graphics drivers or hardware.
My console on an old i5-3330 with intel hd graphics 2500 (which doesn't get driver updates anymore afaik) get's flooded with gles-Errors like this:
[14360:0628/140113.099:ERROR:gles2_cmd_decoder.cc(9709)] [.DisplayCompositor-000 00045D444E370]RENDER WARNING: texture bound to texture unit 0 is not renderable. It maybe non-power-of-2 and have incompatible texture filtering.
I think compatibility mode disables some graphics features so it will work fine.
Don't know if this help narrowing it down but i got this with several electron apps (e.g. Mattermost) on this old computer.
Also, the app is "usable" except for being blank. You can still see the cursor change when you hover the (invisible) new button on the top.

[SamvelRaja]

All, I would recommend you guys to try the solution provided here to resolve this. We figured out that on certain GPU's the app is not rendering.

[Rostanxd]

@dmarkowicz96 ty so much!!... 'Troubleshoot compatibility' , it worked for me. I have Windows 8.1.

[monGanti]

same here 'Troubleshoot compatibility' works, i installed 6.3.0 version on windows 8.1 and i got the blank screen. Following the instructions here helped.

[AnsurM]

What I did to solve my issue is as follows:

Went to:

"C:\Users\Ansur\AppData\Local\Postman\app-6.7.1" (that is where my postman.exe is installed, not update.exe).

Right click, open Properties>Compatibility tab>
Tick "Disable Display Scaling on High DPI Settings"
and
Tick "Run this program as administrator",

And I got my display back and app working fully.

Thanks!

[jzapantis]

Im using Windows 8.1 PRO, and Postman 7.0.9 - had a blank screen.

@eMarv @dmarkowicz96 @orck-adrouin
Thanks the solution worked for me. Weird - I hope running it in Windows 7 doesnt lead to loss of features or issues updating, but happy to have it running on my machine.

Thanks!
