Subject: fix: Adjust caption-removing style call
|
|
|
|
There is a SetWindowLong call that removes WS_CAPTION for frameless
|
|
windows, but Electron uses WS_CAPTION even for frameless windows,
|
|
unless they are transparent.
|
|
|
|
Changing this call only affects frameless windows, and it fixes
|
|
a visual glitch where they showed a Windows 7 style frame
|
|
during startup.
|
|
|
|
The if statement was originally introduced by
|
|
https://codereview.chromium.org/9372053/, and it was there to fix
|
|
a visual glitch with the close button showing up during startup
|
|
or resizing, but Electron does not seem to run into that issue
|
|
for opaque frameless windows even with that block commented out.
