Port the red screen fix from the original repo

[cab404]

Hi there!

There's a problem with newer versions of sway showing red screen on lock.

https://github.com/mortie/swaylock-effects/releases/tag/v1.6-4

This release probably should've fixed that.

Here's a tracking issue:

#3 was just fixed in #20, looks like all the necessary porting and additional development work has already been done?

(Aside from some fallout where a white screen may show after DPMS on->off->on, and noticeable stutter/delay upon locking)

Well, I guess then the only thing left is to make a release, so we can update it's package in distros)

@jirutka ?

is this merged? I'm still using morties branch because this fork/new maintained version is unfortunately unusable due to this error.

This was fixed in df957f1, which is available in the latest release 1.7.0.0.
