Actually there are two bugs - - The original reported issue [0] happens on Sharp panel model 5457. The issue is still unresolved. - A more pervasive issue [1] that happens on more panels is resolved in drm-tip kernel. The fix is not in mainline yet.
As for Ubuntu kernel v5.19, in addition to fix for [1], we also need another PSR fix. This is in the test kernel, please give it a try if possible.
