<pre>Reassigning to i915 to check the workaround in intel_display.c :
/*
* Display WA #0531: skl,bxt,kbl,glk
*
* Render decompression and plane width > 3840
* combined with horizontal panning requires the
* plane stride to be a multiple of 4. We'll just
* require the entire fb to accommodate that to avoid
* potential runtime errors at plane configuration time.
*/
if (IS_GEN(dev_priv, 9) && i == 0 && fb->width > 3840 &&
is_ccs_modifier(fb->modifier))
stride_alignment *= 4;
I think there might be an issue there, because it applies a workaround that
seem to be meant for the aux surface to the main surface.</pre>
