    Few things: First your plugin indentpython should be define above, with the other plugins. Not sure that's the reason, but if not, you'd have issues with that. Then, have you tried commenting each plugin one by one to see if one one them is the reason? Finally, have you tried with another colorscheme (again, in case it comes from this one. I could not find that scheme online so couldn't try with it)? – padawin Nov 10 '20 at 7:54

    Take a look at :h 'visualbell' (which you have enabled). – B Layer Nov 10 '20 at 7:57

That's going to be a result of you having 'visualbell' (alias 'vb') enabled, per your vimrc file. When that setting is enabled any illegal/invalid action that would normally cause a beep/bell sound will instead flash the screen (by briefly inverting the display).

The simple solution is, obviously, to disable it.

:set novb

You can also shorten the length of the flash. See :h 'vb' for details.

If you want to keep the visual bell for specific cases you may be able to disable it only for cases like you describe in your question using 'belloff' (alias 'bo'). An example of its use:

:set bo=backspace

That will prevent the flash only when "hitting <BS> or <Del> and deleting results in an error". Perhaps :set bo=backspace,cursor will do the trick. Check out :h 'bo' for the details. (I believe this requires a relatively modern version of Vim. 7.4.xxx or later where xxx is a value that I'll need to look up.)
