  * :!: Xfce compositor exhibits laggy window dragging when specifically using ''intel'' vs ''modesetting'' (input latency is lower with compositor disabled on both drivers)
  * 2024/12/12: [[games:bsd:devilutionx|DevilutionX]] has odd artifacting at mouse cursor when left-mouse is held down
  * ''glxgears'' does over ''9000'' FPS 8-) with ''intel'' vs ''7000'' modesetting
