<br></div>But there are two more issues (not related to this fix).<br></div>1. Changing Display depth to 4/8/16 shows horrible rendering artifacts<br></div>&nbsp;&nbsp; (those do not occur on squeak)<br></div>2. Since refactoring some parts out of DisplayScreen into MorphicUIManager you<br>
can not change the depth from -XX to XX<br>Display newDepth:8 <br>has no effect if current display depth is -8.<br></div>(This happens on squeak too, verified in Squeak 4.4/Squeak 4.5).<br><br><br></div>BTW found this change for alphaSourceBlendBits8 its way into squeaks vm?<br>
