Mipmap issue with AMD driver 22.6.1 and later Empty Mipmap issue with AMD driver 22.6.1 and later

Recently it seems Windows 10 forced one of my machines with AMD GPU to upgrade the graphics driver to Adrenalin 22.11.1 and that caused a fatal error in Expresii. Specifically, you would encounter an 'access violation' with the program stopping at 'Build2DMipmap'.

Before we get a workaround in Expresii for this issue, it seems the only way for you to keep using Expresii is to downgrade your AMD driver to 22.6.1 or 22.5.1 (WHQL), if you happen to have an AMD GPU. For some systems, Windows 10 may forbid you to downgrade the driver, so if you really need to run Expresii on your AMD GPU, please consider not to even update Windows 10 at the moment.

FYI, if we get lucky, Expresii can get pass the build mipmap and won't crash, but the mipmapping issue still affects the strokes - black color on the edge of the stroke, and the stroke would also 'pulsate'. Hopefully we can fix it soon.
