After I updated my LibreOffice from 5.2.x 32-bit to 5.3.x 64-bit Calc has become sluggish. Moving between cells by pressing Ctrl + arrow keys to jump to the next populated cell is not instantaneous like before. Now, it takes about half a second. The same goes when I click to change tab in the same document, or scroll up or down the document. All these operations were very quick in 5.2.x 32-bit.
Another thing I noticed is that the fonts have changed somehow, although I cannot describe exactly what it is. It is as if they are "pointier", with pixels protruding instead of having smooth lines. This make the smaller fonts a bit less readable.
Should be ready for the final 5.3 release.
Please test with the 5.3.7dev build, from here:
or for 64-bit here:

Thank you for the quick feedback. Will 5.3.7 version also address the font issue?

It does, basically rolling back some of the work for transition to MS DirectWrite Direct2D font rendering to restore some use of legacy MS GDI rendering. Going forward at 5.4 and 6.0 we'll continue to tweak things so there will likely be some regression again.
Thank you! :)
