Subject: disable-redraw-lock.patch
|
|
|
|
Chromium uses a custom window titlebar implementation on Windows when DWM
|
|
is disabled (Windows 7 and earlier, non Aero theme). The native titlebar
|
|
sometimes painted over this custom titlebar, so a workaround was put in
|
|
place to lock redraws in reaction to certain events if DWM is disabled,
|
|
since the code assumes that in that case, the custom titlebar is painted.
|
|
Electron forces the use of the native titlebar, which the workaround doesn't
|
|
take into account, and still locks redraws, causing weird repainting issues
|
|
in electron (and other applications). This patch provides a way to disable
|
|
the redraw locking mechanism, which fixes these issues. The electron issue
|
|
can be found at https://github.com/electron/electron/issues/1821
