Left part of Top bar is not clickable when cursor is at the top edge since 1.3.34
When a cursor is at the top edge, none of the left buttons ('Activities', SomeApp, etc.) can be clicked, they are not highlighted on mouse hover. If I move the cursor 1px down, all works. But it is strange, that the left part of top bar is not clickable by top-edge-positioned cursor, while the center part (clocks&date) and the right part (wifi,battery,language,etc.) are.
I suppose some problem is somewhere in recalculation of this active (or some other) region height: when my system is loaded, all works. But then I open a window or switch to the overview mode (when the left app bar and all-windows overview are shown), this kind of invisible top-left border appears again. I tried to disable all extensions, clear the cache of packages and reinstall the whole system (with pac.manager's "--overwrite='*'" option), but nothing helped.
This started since I updated to Gnome 1.3.34. Arch Linux has published some updates since then (my current version of the "gnome-shell" package is 1:3.34.1+12+ga43c22e3-1), but nothing with this bug changed. I have not found any discussions on this bug before starting this issue.
Thanks
