Segmentation fault/non-working renderer (default, P2D, P3D)

Description

Graphics not updated correctly or segmentation fault, depending on which renderer is selected

Expected Behavior

Below code should just work fine (as it does with FX2D)

Current Behavior

• graphics is not updated with default renderer size(300,200);
  It works fine if I comment out the noLoop()

• Segmentation fault with P2D/P3D renderer size(300,200,P2D) (see below)
  when doing first key press

• works just fine with size(300,200,FX2D);

Steps to Reproduce

void setup() {
  size(300, 200, P2D);
  noLoop();
}
void draw() {
}
void keyPressed() {
  background(255);
  text("x", 10, 10);
  redraw();
}

1. type any key

Your Environment

• Processing version: 3.4 (macOS), 3.3.7 (windows)

首先，在列出的 Processing 版本上使用默认、P2D、P3D 和 FX2D 渲染器复现 sketch，然后检查报告的 hs_err_pid8425.log 和有问题的 libGL.dylib frame。完成的标准是：使用 noLoop() 的 sketch 在第一次按键后会更新，并且 P2D/P3D 不再发生 segfault。
