From 60d873bd22121a089101fe6058e0e6aba0467234 Mon Sep 17 00:00:00 2001 From: Jeroen Bakker Date: Mon, 6 Apr 2020 16:31:22 +0200 Subject: GPU: Panel Drag Widget Drawing Performance MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The 10g Intel/Win driver doesn't work well with our emulated intermediate mode. This patch alters the drawing of the drag widget of the panels to reduce unneeded drawing. The previous method would draw 16 boxes per widget. This new way would cache this drawing in a GPU batch and just move the matrix around.
