--- Comment #8 from synthetix <[email protected]> --- Replying here because my other bug report was marked as a duplicate. Yes, I have reason to believe this is absolutely related to HDR. The reason is the backlight driver is triggered based on the brightness of the content on-screen, and in my case this cannot be disabled. I confirmed this by observing the brightness values in /sys/class/backlight/. For example, if I minimize and maximize a window with full white, the backlight values in /sys/backlight change without me doing anything else. So something is clearly manipulating the backlight driver based on whatever the compositor is doing. If you have a suggestion of somewhere else to troubleshoot this behavior, I'm open to suggestions. But this is problem didn't start until the new SDR->HDR feature was added. -- You are receiving this mail because: You are watching all bug changes.
