Summary

The shader is bugged in the first time open the game

Steps to reproduce

Install Minetest (yes, this bug only appear first time) Open the game Set video driver to OGLES2 Turn on shader open a world or join a server

Can reproduce (Nokia 5.4), happens on 5.5 if you switch from OGLES1 to OGLES2, enable shaders and then join a world without first restarting Minetest (assumedly tries to compile OGLES2 shaders on an OGLES1 context... which does not work). Does this still occur after you've restarted Minetest?

Worth noting the same reproduction steps crashes the game on 5.6.0-dev and starting it again works of course since it's been restarted.

its only happen in first time open the game

[oong819]

this probally a duplicate of something like setting dont be saved in first time open the game

[rollerozxa]

This would be user error. Changing the video driver is an advanced setting and the description for the setting states a restart is required for the setting to take effect.

The real issue would seem to be that the shader settings are immediately being enabled in the main menu settings tab since it checks for the setting's value rather than what Irrlicht video driver is actually running at the moment.

Needs re-testing.

As i remember, i did the all the thing in reproduce steps in 5.7.0 (normal thing i do every time i re-install Minetest) and it's completely normal, but i will not trust my memory, but i also ran out of storage space to install Minetest
