Strange graphical glitches: missing parts of text, random green squares

This bug comes in two parts: one part is an issue with fonts and the other is an issue with images.

Font rendering

As seen below, fonts often appear garbled and some characters don’t show at all. This appears to be an issue with all instances which render text. Originally I thought the fonts were corrupted, but even after reinstalling Roblox, the fonts still rendered this way.

Oofed images

Sometimes a similar effect to the garbled fonts happens with images. I’m pretty sure this only happens with images rendered on surfaces, including textures and decals. The images appear very messed up, with a sort of grid of random green squares covering the image. Unfortunately I was not able to get any screenshots, but if I do I will add them below.

OS - Windows 10 Pro 64 Bit
CPU - Intel Core i7-8550U
GPU - AMD Radeon R7 M460
Storage - 128 GB SSD (System disk) and 1 TB HDD

Intel and AMD together? I’m surprised the universe is still intact too.

Just want to add that this does not seem to occour in Studio.
