With a rate 1/2 you can’t expect to correct more than 5.5% of errors.

Actually I wrote smartwatch but I meant GPS watch. I recently bought a Garmin and there’s no wireless charging for it.

Are you talking about wlr-randr? Because its --transform argument only accepts normal|90|180|270|flipped|flipped-90|flipped-180|flipped-270, not any transformation matrix. Maybe its just a limitation of the command line tool and it could be modified, I don’t know, I haven’t been too deep in the code or the protocol specifications. It also looks like it only works with wlroots based compositor.

I wish smartwatches were included too so that I could travel with just one charger and one cable. I guess waterproofing a USB-C port is not that easy though (for the ratings those watches usually have).
