Description:
On Linux the drawing code in Calc appears to have issues with fractional scaling that results in text/line art corruption.  This includes cell lines breaking up, and pieces of text being cut off/overdrawn (see screenshot where issues are identified in red).  On window blur the issues resolve themselves.

Steps to Reproduce:
1. On an X11 Linux system with a high-DPI display open up a new Calc document.
2. Populate some cells with content.
3. Use the arrow keys to move around cells, soon on-screen corruption will begin to appear.

Actual Results:
Text and line art is corrupted after moving around a few cells.  Can also be triggered by typing into a cell.

Expected Results:
There should be no cropping/overdrawing/misalignment.


Reproducible: Always
