The background and text of buttons are transparent if Minecraft window wasn't rendered at startup

If you minimize or cover Minecraft window fully by another window at startup, the text and background of buttons will be transparent, it started to appear since some ui drawing optimizations have been added in 24w11a.

Steps to reproduce:

1. Start Minecraft.

2. As soon as it opens, minimize the window.

3. Unminimize the window after about 5-10 seconds.

4. Notice that text and background of buttons are transparent.

Notes:

• Mutter (the GNOME compositor) seems to have an optimization, where if the window is fully covered by another window or the it is minimized (you can observe it by looking at ingame fps graph (f3+2) after the game was minimized or covered by another window for a few seconds

• ), it contents won't be rendered, which might have caused this issue.

• "Welcome to Minecraft" screen, Minecraft logo, Minecraft version and type text, accessibility and language settings icons are not affected.

• It affects both buttons with animated background and without.

• Resizing the window fixes the issue.
