MyPaint becomes is just as responsive as with XAA, except for the panning. GIMP is a jerk (I get cases where I draw a curve and the middle of it gets flattened into a straight line); But I haven't been painting anything with GIMP recently so I don't know whether it's also a jerk with XAA. 3d performance in Blender is fairly poor (but noticably better than with XAA) Panning in both MyPaint and GIMP (and Firefox) is still noticably slower. Fast smooth panning is important to me, so I will switch back to XAA. _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
