I get bad logs from frontend when I enable --loglevel debug

CPU is Intel 11th gen. Core I5.

It looks like
2022-07-15 18:12:42.707452 D [18722/18722] CoreContext
mythrenderopengl.cpp:1433 (CreateShaderProgram) -
#version 110
#define lowp
#define mediump
#define highp
#line 1
attribute vec2 a_position;
attribute vec4 a_color;
varying vec4 v_color;
uniform mat4 u_projection;
uniform mat4 u_transform;
void main() {
gl_Position = u_projection * u_transform * vec4(a_position, 0.0, 1.0);
v_color = a_color;
}
etc...

Attached the log file of the frontend.
How to debug, fix this issue?

I've seen that before. I think Mark did that intentionally so you
could see what the shaders are being programmed to do. I've always
just ignored it.

It should probably be moved from VB_GENERAL to something else. Maybe
VB_GPU or VB_GPUVIDEO? Or give it its own flag.

David,
thank you for confirmation. It popped up when I tested PR #606
<https://github.com/MythTV/mythtv/pull/606> on master,
using a new built PC with Intel Core 11th gen.
Not sure, if this will be shown on earlier versions. I will check this.
