Can you try the workaround described in this bug, also?

However, I face one more issue: When Scroll through pages, the font artefact/texture changes and looks kind of bold and not anti-aliased. it is corrected once I press ALT+F1 or do other activity like scroll or move to other tab. this issue existed along with the original problem discussed.
will try to take screenshot.

Thank You for the Support.
