Minecraft: Very glitchy rendering with Fabulous! settings
Description
When the Fabulous! video settings are chosen in Minecraft Java, the rendering becomes very glitchy and unusable. I have reported this as a bug for Minecraft (MC-209762), but I have been advised to report it to Mesa too since the two have had incompatibilities in the past.
I have disabled mods and the bug still occurs. Notice that in the big window, the block in the centre is regular clear glass, while the others around it are black stained glass that add another semi-trasparent layer. With fancy settings, notice how the rain particles are only rendering behind the clear glass block Figured out that this is intentional behaviour with fancy graphics. Several other bug reports in the Minecraft bug-tracker talk about a warning when switching graphic settings to fabulous, but I haven't met any with my system.
I have attached screenshots of the same spot, with rainy and clear weather, on fancy and fabulous video settings for comparison.
