This is a standard adhesion problem with glass beds:

Glass beds are super level, but they transfer heat less good than metal and BuildTak. This also means that not every spot always has the exact same temperature, which can come from a lot of things, for example, a draft from the open window jitting that corner and causing lifting.

There are some super easy and cheap solutions:

• Painters Tape adds a little bite to the surface
• a thin PVA (Gluestick, wood glue, hairspray, or specifically designed sprays for 3D printing) bonds the first layers much better to the glass
• for ABS, ABS-in-acetone-slurry is a known bed adhesive
• measure the top of the bed temperature - you will find out that the increased thermal capacity of the bed+glass sheet means that your set bed temperature is not reached on the bed surface. Adjust as needed!
• prevent any and all draft (close windows and doors)

There are some super easy and cheap solutions:

• Painters Tape adds a little bite to the surface, but you need to level to its top.
• a thin PVA (Gluestick, wood glue, hairspray, or specifically designed sprays for 3D printing) bonds the first layers much better to the glass
