Public bug reported:
Sometimes the cursor tracking is wrong when using chromium-browser as in
the pointer on the screen is pointing to one place but chromium sees it
in another. If I move the cursor outside of chromium, other applications
track it fine. Most of the time things are ok with chromium, but when
this happens the text in the web page also goes slightly fuzzy.
Thankfully, a workaround is simply to resize the window (it doesn't seem
to matter how much). After which, the text is no longer fuzzy and the
mouse is tracked correctly.
