Bug ID: 511801
Summary: New "Extended Dynamic Range" feature is pointless,
annoying and can't be turned off
Classification: Plasma
Product: kwin
Version First 6.5.0
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
On Debian forky, the new Extended Dynamic Range feature is always on, no matter
if it's checked or not in the display settings. This setting keeps messing with
the brightness of the display through the kernel backlight interface and it's
extremely annoying. The result is steppy brightness on an AMD laptop that's
abrupt, jarring and doesn't even syncronize with what is happening on the
display. This is a totally useless feature that should have never had any time
wasted on it. If the user wants HDR, they go buy an HDR display which works
correctly and doesn't try to be clever by manipulating the very laggy backlight
driver.
What's worse is the bug forces this awful feature ON. It can't be disabled.
Epic fail.
Please respond with a way to disable this featue manually so it can't mess with
the backlight. If I have to disable all backlight control by keeping Plasma's
hands off it and adjust the display manually through /sys/class/backlight
myself, so be it until this bug is fixed.
