Room Grid Aliasing #477

Closed RobertBColton closed 4 years ago

RobertBColton commented 4 years ago

This seems to be another regression that occurred between 1.8.6 and 1.8.10 where the former does not have the issue. The problem is the grid in the room editor becomes extremely aliased and flickery when panning.

v1.8.6 (no aliasing) v1.8.10 (aliased)
1.8.6 No Aliasing 1.8.10 Aliasing

I'm sorry this issue was not a regression. We've all been seeing this for a while now and it just has to do with Windows upscaling the Java2D graphics and is obviously subpixel alignment related. These two screenshots I took to compare are different horizontally. If I go back and check v1.8.6 again I can in fact reproduce the aliasing that appears on the right.

However, that doesn't necessarily mean we couldn't apply a tweak to make this not so bad.

It goes away if you set OpenGL acceleration in preferences, such likely the dreaded D3D9 issue.
