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
