Subject: [PATCH] xwl: Do not refresh the x11 Clipboard while fetching
|
|
|
|
At the moment there was a race condition when putting something into the
|
|
keyboard from XWayland apps. The clipboard manager would announce a new
|
|
thing before we'd submitted it all resulting in a broken state.
|
|
|
|
This change detects when it's fetching and will only refresh the source
|
|
after everything has been sent.
|
|
|
|
BUG: 424754
|
|
CCBUG: 412350
