 |
|
Hi, after recent upgrade to Plasma 6 and switch to default Wayland, fulls-screen applications (games) no longer upscale* correctly. Instead, I get small display area, not even centered, surrounded by black border. Is this to be expected or can it be fixed? Thanks.
*it probably wasn't upscaling but rather a mode change on X |

Out of curiosity, does toggling 'Legacy Applications (X11) Apply scaling themselves' and 'Scaled by the system' in SystemSettings>Display & Monitor have any effect?
It would probably help to know what specific applications and games you are referring to. Are these native applications or are you using wine, etc. |

| Toggling those settings didn't have any effect. I am experiencing this with both native eduke32 and Stronghold Crusader in wine, so it seems to be generic issue. When I start X, instead of Wayland session everything works fine. |

That is good information. I am sorry I am not able to offer much help.
Is it possible to force wine or your programs to run under Xwayland by using
GDK_BACKEND=x11 with the command? For example, I currently do this with Thunderbird:
| Code: | | GDK_BACKEND=x11 thunderbird |

That didn't help either.
Relevant lines of terminal output from eduke32:
| Code: | 0.0996s INFO| Initializing SDL 2.28.5 (SDL-release-2.28.5-0-g15ead9a40)
ATTENTION: default value of option mesa_glthread overridden by environment.
0.2828s INFO| Using 'x11' video driver.

It appears to be the same whether run with or without GDK_BACKEND=x11. |
