I believe I have found a bug!
Manjaro Xfce 20.1.2
I installed Notes 1.8.1 from Pamac: it seems that Notes is able to ‘capture / kidnap’ the cursor & suddenly my typing has gone blank. Clicking on the field / block or even Firefox address bar does NOT bring back the cursor…
I have to go back to Notes & click ‘X’ (which puts it back into the tray), then I get control back & clicking on the field / block or Firefox address bar works again. Sometimes, when Notes is left running on the screen & the screen times-out, I cannot login via lightdm again because typing has gone blank - this is SERIOUS & I have to POWER-OFF/POWER-ON to bring back the laptop again. During the moment which Notes has capture / kidnap the cursor, my typing does NOT appear in Notes either…
