Bug 304469

I'm not very technical, so the screen shots I've provided in the wine bug provided in the url probably says a lot more than my thousand words description. 

I've noticed with several 3d accelerated wine applications that running them in full screen mode would fail if there was a plasma panel at the top or left-handed edge of the screen (or rather, as this was probably an artefact of running an application in a resolution lower than the desktop, the saliant point is probably any overlap with a plasma panel) and result in the screen assuming the resolution the application should have, but the application would get what looks like an unmanaged window with an attached plasma bar and being pushed off-screen by just as many pixels (as plasma bar+application is naturally wider than application alone).  

or as Henri Verbeet summarised it "The impression I get from your description and screenshots is that setting the display mode actually work fine, but the application window is never resized
from its original size."






Reproducible: Always

Steps to Reproduce:
this is fairly obviously going to be sorted under "can't reproduce" as it involves non-free software, but as I don't know of any free applications I could try with, it'll have to do.
1. install wine and temple of evil
2. make sure you got a plasma panel, set as always visible, at the left-hand edge of the screen
3. launch Temple of Evil
Actual Results:  
Application will launch, the "screen" will take the dimensions of the introductionary movies (logotypes etc), and it looks like it attaches to the plasma panel (no I don't think it actually sticks, but that's what it looks like..) after this the "window" will not resize even if resolution in game is changed, which may result in a game of 1280x1024 being stuck in a 1024x768 pixels large window.

Expected Results:  
Application will launch, screen take dimensions of introductionary movies, when xrender (which is what I think wine uses) tries to change the resolution as used by the game proper, the window is resized to match the new (higher) resolution. Plasma panel is expected to be excluded.

Setting plasma panel to auto hide or moving it to an area where it won't overlap with wine works as a work around. Similar problems (presentation differs slightly) can be observed with Source and Unreal engine games. Manually configuring the desktop to using the same resolution as the application will use before launch is another workaround. Software rendered games are not affected.

Composing does not seem to be a factor, as I get the same results with and without it.
