Description

I think what is happening is that the texture is too narrow so the font rendering stacks up and makes it larger than GL_MAX_TEXTURE_SIZE height (attempting 4096x20650). If I'm understanding correctly, it seems that glTexImage2D was failing with GL_INVALID_VALUE but it wasn't being handled.

The proposed fix is to increase the texture width.

Note that I really have no idea what I am doing with any of this but it seems to fix the issue on my machine.

Note that XWayland + Nvidia doesn't have this problem nor very old Intel machines.

Closes #10287
