@emilk I've marked this ready. I might disclose the motivation of this, now that i initially forgot.
I'd like to contribute to some points in #3742 in particular linux issues.
Unfortunately this pr din't immediately fix what I hoped fir. However there are some interesting fixes we might hit down the line. Perhaps its ok to move on from this?

I appreciate you wanting to help out with Linux!

I think bumping the winit version for this repository makes sense, i.e. updating Cargo.lock, but by also updating the versions in the Cargo.toml:s you are effectively forcing downstream users to update to. This means for instance that if a bug is found in winit 0.29.7 then users of eframe cannot downgrade to 0.29.6.

Usually we should only set a minimal patch version in a Cargo.toml if we absolutely depend on that version.

Therefore, I suggest reverting the changes to the Cargo.toml files and keep just the changes to Cargo.lock.

(tip: in case you don't know, you can update a dependency in a Cargo.lock file using cargo update -p winit)
