Description：
Signs dyed with glow ink sac create heavy extra GPU rendering load from the glowing text effect, which leads to a sharp drop in frame rate.
While exploring my built structure, my FPS plummeted suddenly and my character froze completely. I isolated blocks and entities in my viewport with controlled variable testing, and confirmed that glowing signs are the cause of the performance issue.
Steps to Reproduce：
Place 20 signs consecutively on one wall.
Apply glow ink sac to each sign one by one to enable the glowing text effect.
Monitor frame rate continuously: the initial FPS stays at 220, and it gradually drops down to only 30 after all signs are converted to glowing signs.
Tips：The frame rate value is displayed on the first line at the top-left corner of the screenshot. The Chinese character "帧" in the image stands for FPS.
Environment
13th Gen Intel(R) Core(TM) i9-13980HX (2.20 GHz)NVIDIA GeForce RTX 4080 Laptop GPU (12 GB)

sorry,i forget about this. multiplayer world(i will test on single tomorrow),Both Vulkan and OpenGL.
there are 3 buildingsin the picture.when they are in my view.only 10-30FPS before i change the signs from glow ink to just black, after that FPS come to 90. but today , i test again the signs ,they donot change my FPS, but the FPS in the town dont change , still under 100. if i move quickly , it will be 50 FPS. if i dont see them 300+FPS. SO i cant figer out whats the reason.
is it because i upgrade theworld from 1.20.4 to 26.2？（this did not happen in1.20.4，i can always have200+ FPS）
these 3 buildings used many signs and display frames actually, is it the reason?
My all-item farm only runs at 30 FPS in empty chunks because of tons of entities（mainly chests and signs.）
are they the same reason
if you want i can give my world to you or you can come to my world for testing
i test on a singleplayer world use save game file same as the sever ,same FPS when sea those buildings. signs didnt chang FPS to much anymore.
so now i have no ideals about whats going wrong , may other bugs i dont now , and happened just few days and let all players only 10 FPS when they sea that building.
