我正在使用 Android 版 LibGDX。我的片段和頂點著色器如下片段著色器：#ifdef GL_ES#define LOW lowp#define MED mediump#define HIGH highpprecision mediump float;#else#define MED#define LOW#define HIGH#endifvarying vec4 v_color;varying vec2 v_texCoords;uniform sampler2D u_texture;uniform vec2 oneOverResolution;vec2 frgCOverRes;void main() {   frgCOverRes = gl_FragCoord.xy*oneOverResolution.xy;   frgCOverRes.y = -frgCOverRes.y+1;   vec4 c = texture2D(u_texture, frgCOverRes);   gl_FragColor = c;}頂點著色器：attribute vec4 a_position;attribute vec4 a_color;attribute vec2 a_texCoord0;uniform mat4 u_projTrans;varying vec4 v_color;varying vec2 v_texCoords;void main() {    v_color = a_color;    v_texCoords = a_texCoord0;    gl_Position = u_projTrans * a_position;}但我讀到highp與某些設備不兼容。而且也沒有使用過（中、低p也沒有使用過）。所以我要將片段著色器更改為以下代碼：#ifdef GL_ESprecision mediump float;#endifvarying vec4 v_color;varying vec2 v_texCoords;uniform sampler2D u_texture;uniform vec2 oneOverResolution;vec2 frgCOverRes;void main() {   frgCOverRes = gl_FragCoord.xy*oneOverResolution.xy;   frgCOverRes.y = -frgCOverRes.y+1.0;   vec4 c = texture2D(u_texture, frgCOverRes);   gl_FragColor = c;}我使用 9 作為 minSdkVersion。我已經在模擬器和我的手機（華為j6ii）中測試了這段代碼。但對其他設備有疑問。這個片段著色器是否與所有設備兼容？
