Describe the bug Tooltips are truncated when text size is configurated over 100%

To Reproduce Set text size at 125% image Go on a page with hints (for example wikipedia :https://fr.wikipedia.org/wiki/Wiki) hover a text/button with the hint several times

Expected behavior the hint tooltip should be correctly shown like on other browser or with a 100% text size configuration

Actual behavior image

Versions :

Additional context Does the problem reproduce with the cefclient or cefsimple sample application at the same version -> yes

Does the problem reproduce with Google Chrome at the same version-> no

It worked with version 108.4.130

Please test in version 126 or newer. Please test cefclient/cefsimple with --enable-chrome-runtime.

Also reproducing it with version 126 and --enable-chrome-runtime

At 125% scale, if you hover the text multiple times, sometimes it will display correctly and sometimes not. It always displays correctly for me at 200% scale. I suspect this may be a rounding error in computing either the text size or the tooltip size.

I'm not able to reproduce this problem on Windows 11 using M130. Still reproduces on Windows 10.

Confirmed that this is fixed on Windows 10 by reverting the above patch.
