Hi,
I'm using wlsunset 0.2.0 on Intel Iris Xe, logs don't show any errors
but output starts looking corrupted after around the 4th or 5th
adjustment until I kill wlsunset. The workaround for me is to set
custom sunset/sunrise and duration to 0.
Yeah, there are known issues with Xe and continuous gamma updates. Not
sure why - I have seen it on a colleagues machine, but not having one
myself makes it a little hard to debug.
I'm not sure if the issue is wlsunset, wlroots or kernel driver. The Xe
hardware and kernel driver handles gamma very weird and very
differently as the hardware implements non-linear gamma LUTs, but the
user-space API is linear.
I tried another gamma control app and it had also had some problems on
this hardware during updates although it would eventually correct
itself, curiously redshift on X11 transitions smoothly on the same
hardware. For now just doing the 1 shot corrections is enough for me
but I'll give it another try when the next versions of sway and
wlroots lands. Thanks.
