Solved After another packages update (pkg 2.2.1), tor-browser broke.

[USerID]

The essence of the problem: if you try to click the "Attach file..." button in proton.me, then a window opens, you can't select a file, when you try to stretch the file selection window with the mouse, the window "breaks". Sometimes not the entire file selection window appears, but only the window title.
I highlighted all the delights with a red marker.

And what are these little squares instead of letters? I don't use languages other than English in the names of the catalogs.

I deleted the cache and config of the browser itself, reinstalled the browser - did not help.
BEFORE THE UPDATE OF the pkg itself and packages (see the list) this did not happen.
Use X11.

The problem does not occur if you work with proton.me in Firefox. Only in the Tor browser...
Does anyone have this problem? Or am I the only one who gets exclusive bugs?
Moreover, the window ("Attach file...") is distorted in the most arbitrary way.
But you can close this window using the Escape key.
