Cirrus CL-GD5429: graphics corruption in DOS after loading windows 95

Machines: AMI 486 clone 16 MB, MR 386DX 8 MB, most likely all of them. Windows 95 RTM.
800x600 desktop with the included driver. Launching a fullscreen dos box or restarting in ms-dos mode you get wrong characters in text mode and no Doom startup banner. Doom 2 doesn't work, you get vertical lines with graphics junk.
Additional problem: slightly wrong colors with the included driver and much worse in 16 bits (very bad).
Discussed here:

dondiego , bro , this is not PCem but pcem clone, and anything with 86box will not be discussed here, you can download PCem source from
https://bitbucket.org/pcem_emulator/pcem/downloads/ and compile yourself, then if anything is wrong it will be discussed here.
Please dont mention 86Box here as it is NOT PCem, and this forum is for PCem ONLY, not 86Box. if you care, you would read the very topic above yours
https://pcem-emulator.co.uk/phpBB3/view ... ?f=2&t=502 .
Dont worry , i hope i didnt offend you in anyway , but this threads at very top are to be read , so no 86Box HERE
Take care

Of course it's a PCem bug report, i posted that link becouse i reported it there first (i could not register here) and some information there could be helpful.
Actually there are two bugs in PCem.
