Description David Jaša 2015-11-25 16:16:45 UTC

Description of problem:
qxl driver offers resolution that don't fit to video memory (> 2560x1600 or 2048x2048)

Version-Release number of selected component (if applicable):
qxl-win-unsigned-0.1-24
guest OS tested: XP, 64b Windows 7

How reproducible:
reproducible on XP
not reproducible on 64b Windows 7 (32b 7 not tested)

Steps to Reproduce:
1. run VM with default video memory settings (ram/vgamem/vram: 64/16/64 MB)
2. install qxl driver
3. change resolution from OS applet (right click Desktop -> Options)

Actual results:
modes beyond 2048x2048 or 2560x1600 are offered on XP

Expected results:
maximum offered modes fit to 16 MB (aka <= 2560x1600, 2048x2048) on XP as well

Interesting, we'll investigate but not in the scope of 3.6, definitely not a blocker.

Comment 3 Pavel Grunt 2015-11-26 10:13:28 UTC

It offers the higher resolution but with reduced color depth (16b instead of 32b)
