rendering artifacts in xterm

Created attachment 171557 [details] rendering artifacts in xterm SUMMARY When screen scale factor is larger than 100% and X11 scaling option is set to "Apply scaling themselves", one-pixel rendering artifacts can be observed in XWayland applications. Mostly noticeable in raw X11 applications that take use of something like "partial redraw" (e.g. xterm and LibreOffice with `SAL_USE_VCLPLUGIN=gen`) STEPS TO REPRODUCE 1. Set screen scale factor to 200% and X11 scaling option to "Apply scaling themselves" 2. Open xterm 3. Move mouse around menu items in xterm OBSERVED RESULT One-pixel lines on the edge of redraw areas. EXPECTED RESULT No rendering artifacts.
