oneplus-bacon: redscreen kernel patch / msm fb refresher

Applied red screen kernel patch as described in https://wiki.postmarketos.org/wiki/Troubleshooting:display Effectively fixes the red screen on Weston.

Added msm-fb-refresher to APKBUILD to fix display refreshing.

The display now works properly in Weston, but unfortunately the screen is blue in Plasma-mobile, and X11 crashes in xfce

This is how the screen looks in Plasma-mobile.

What is really strange is that the kernel patch successfully changes the bits_per_pixel of the framebuffer to 24, when installing weston, which makes the display works correctly in weston

In weston cat /sys/class/graphics/fb0/bits_per_pixel 24

Instead when choosing plasma-mobile in pmbootstrap init, the bits_per_pixel goes back to 32, regardless of the kernel patch, so the screen is garbled

In plasma-mobile cat /sys/class/graphics/fb0/bits_per_pixel 32

Do you know why this happens?

I opened the issue #204 (closed) which seems more appropriate to discuss this.
