Inverse Tonemapping doesn't quite seem to work in Gamescope. #1034

Open isaboll1 opened 9 months ago

isaboll1 commented 9 months ago

When launching gamescope using --hdr-itm-enable, there doesn't seem to be any changes made for SDR content being played on HDR screens, with respect to Inverse Tonemapping.

Investigating a bit, the ITM boolean value doesn't seem to be passed in the process of binding pipelines, unlike how it was when the feature was first introduced, despite pipelines seemingly allowing for the boolean value . Likewise, the constant id used for ITM in pipelines seems off compared to what's expected with regards to descriptor sets .

At least according to my tests, it seems that the option --hdr-itm-enable, really doesn't kick in and doesn't change anything on my KDE Plasma 6 it just looks the same as if SDR content is running on HDR which it already does without gamescope.
