While DSA members cannot join the PSL or vice-versa
This is not true actually. At the most recent DSA National Convention this year the anti-democratic centralism clause was repealed, so there is no problem being both part of DSA and PSL anymore
Can you provide a source? I haven’t heard that perspective before but it sounds interesting
You can use Gamescope to get HDR working. On Steam games I use this template as the launch option for games (2160x3840 is the resolution, 240 is the refresh rate):
DXVK_HDR=1 gamescope -f -H 2160 -W 3840 -r 240 --hdr-enabled -- %command%

PSL doesn’t allow dual membership with another organization with democratic centralism, but DSA doesn’t have anything like that and isn’t a political party so it’s fine as far as I know. Feel free to correct me if I’m wrong though
