vcl/source/outdev/text.cxx using base position for better rounding a.k.a. "dancing characters" in OutputDevice::ImplLayout seems to be a reason this happens commit 1bd5948782dad86141356ebbb4fad37e5181c296 Author: Vladimir Glazounov <vg@openoffice.org> Date: Wed May 28 11:30:40 2003 +0000 ... 2003/05/12 14:44:36 hdu 1.145.4.3: #109377# better rounding for pDXArray, CJK underline position there seems to be a one pixel different in the starting pos from when the editengine is "active" and when it's not which results in the dancing characters we still see

That makes the kerning stable on entering the cell for me. Done in trunk, backport to 7-3 in gerrit

I verify the kerning change is gone. The two bottom lines do move to the left, but that must be some other issue.
