Can you test the runtime screen resize?
I did make a fix to that portion of the code for Version 0.4.158, but all the
testing was done on UMS code.
The KMS portion is unproven, and I will like to see how robust the newer screen
resize code is.
When you do the testing, please change the screen resolution between a really
large screen size and a really small screen size (i.e., 1920 X 1080 down to 640
X 480), and repeat this quasi-randomly between many screen resolutions between
640 X 480 to 1920 X 1080.
If the code is working properly, it should not crash at all.
For the UMS code, the screen resize is now very robust, and I have confirmed
that this works perfectly with 5 different VIA chipsets (CLE266, KM400, VN896,
VX700, and VX800).
