## Colors look incorrect when recording HDR (with hevc_hdr/av1_hdr) or using an ICC profile
KDE Plasma version 6.2 broke HDR and ICC profiles for screen recorders. This was changed in KDE plasma version 6.3 and recording HDR works now, as long as you set HDR brightness to 100% (which means setting "Maximum SDR Brightness" in KDE plasma display settings to 203) and set color accuracy to "Prefer color accuracy". If you want to convert HDR to SDR then record with desktop portal option (`-w portal`) instead.
I don't know how well recording HDR works in wayland compositors other than KDE plasma.
## GPU Screen Recorder starts lagging after 30-40 minutes when launching GPU Screen Recorder from steam command launcher
This is a [steam issue](https://github.com/ValveSoftware/steam-for-linux/issues/11446). Prepend the gpu-screen-recorder command with `LD_PREFIX=""`, for example `LD_PREFIX="" gpu-screen-recorder -w screen -o video.mp4`.

@@ -250,3 +250,9 @@ Support high quality scaling with -s by using lanczos.
Support spanning multiple monitors with region capture. This would also allow the user to record multiple monitors at the same time, the same way screen-direct works on nvidia x11.
When webcam support is added also support v4l2loopback? this is done by using avdevice_register_all(); and -c v4l2 -o /dev/video0; but it needs to output raw data as well instead of h264 and possibly yuv420p. Maybe add a -k yuv420p option to do that.
Do proper exit, to call gsr_capture_destroy which will properly stop gsr-kms-server. Otherwise there can be zombie gsr-kms-server on error.
Replace all scissors with clearing textures if the cursor hits the outside of the frame image.
Cursor position might be slightly wrong on rotated monitor.
