Exiting visual causes weird side-effect

[trev-dev]

When I enter, then exit visual mode, the whole buffer highlights briefly.

If I yank something, then enter and exit visual mode, the last thing I yanked highlights again.

I disabled all of my other plugins and could still reproduce it.

Thank you for your report. Can I ask about your environment? (OS, vim version, terminal, ...) When the whole buffer is highlighted, is the buffer text in a register?

Reproduced both on nix via WSL2 and NIxOS

The highlighting on exit visual does not impact my registers. Yanking and highlighting does, as intended.

I finally found the reason. Probably, you are using `'go-a' or auto-select. Vim-highlightedyank did not work well with the auto-select feature.

Please reopen freely if you still find problems.

@machakann Yep, that was it. I had not set my clipboard option and it comes with autoselect by default
