SDL2: VRAM memory leak when borderless fulscreen screensharing

[BitKovin]

I'm using GLEW + SDL2 and noticed weird vram leak when screensharing. When using SDL_WINDOW_FULLSCREEN_DESKTOP and screensharing whole screen using Discord(only tested with it) VRAM starts to drain at very fast rate. I made minimal example that triggers this problem on my PC.
