@Nemra1 have you try the latest build ? http://dl.nwjs.io/v0.23.7/
may I know what platform are you using ? and the version ?

and from your window manifest
resizable should be false
frame should be false

also please read the doc
http://docs.nwjs.io/en/latest/For%20Users/Advanced/Transparent%20Window/

im using 0.23.7 in windows 8.1 64x and also ido every thing right but no luck

[jtg-gg]

I've just tested it on Win 8.1 pro, using nwjs 23.7 x64 version using this
transparency-5989.zip

I can get the transparency works

@jtg-gg ~~~I tried the config and html files provided above on a win7 32x machine, with nw v23.6, the window created transparently but no html content rendered, then I open the window devtools, no js error occured, I can still operate the dom & js in devltools. Then I change to use nw v22.3 to run again, the transparent window was created with correct html content rendered.~~~

I downloaded nw v23.7, the html with transparent window is rendered correctly. But I'm sorry that there's still same problem described in #5989 😢

@aprilandjan which issue ? black screen after waking up pc from lock ?

[aprilandjan]

@jtg-gg yes

[jtg-gg]

@aprilandjan I can't reproduce on my win 7 virtual machine
does this happen with win 10 ?
what gpu are you using for the win 7 ?
does this happen with other win 7 machine ?

[Nemra1]

@jtg-gg im its same thing but not work

[Nemra1]

the problem her when im add "transparent": true, and run my dos command C:\nw0267\nw.exe C:\app
the nwjs.exe not showing any more and running in background like this screen

to back to work i need to"transparent": false and, must kill nwjs.exe manual and run dos command again

@Nemra1 can you try to use my sample app https://github.com/nwjs/nw.js/files/1168696/transparency-5989.zip ?
and also can you run with this extra param "--enable-logging"

[aprilandjan]

@jtg-gg Sorry to reply late! I tested on a win7(i7-6700, AMD Radeon R5 340X) with nw v0.23.7-sdk-ia32, I can still reproduce in following steps:

1. minimize nw window;
2. lock windows, click switch user, choose the previous logged user and back to windows;
3. restore your nw window
4. the transparent background in nw window became black.

And I found that in the same win7 machine if I did not switch user after lock windows, there's no problem; I also tested the same program on a win10 machine, it works very well.

Hope this help!

thx @aprilandjan, I can reproduce the bug,
but fixing it might take some time, my dev env is win10

[jtg-gg]

@aprilandjan I found a work around, if your run the transparency with "--disable-gpu-compositing" and "--force-cpu-draw" it works,

do you really need gpu compositing ?
if you don't want click through, you can "cheat" by setting the alpha value to 1, it look like total transparent

[sksar]

set frame:false and transparent: true
It should do the trick

[jtg-gg]

@aprilandjan I've made a fix for the issue, actually the black background also happens if you change theme to basic, then back to aero glass
@rogerwang I've made a pull request nwjs/chromium.src#96
please also patch nw26

[rogerwang]

This is fixed in git and will be available in the next nightly build.

[aprilandjan]

@jtg-gg Thanks! I'll give it a try once it became available!
