Bug ID: 404634
Summary: Kwin crash on SDL2 application startup
Product: kwin
Version: 5.14.5
Platform: Slackware Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: hanni...@astral.lodz.pl
Target Milestone: ---
Application: kwin_x11 (5.14.5)
Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.20 x86_64
Distribution (Platform): Slackware Packages
-- Information about the crash:
Kwin crash when I fireup my SDL2 application. It only apperars only on first
and second kwin instance (I mean, orginal - and second started automatically
after crash). Third one seems to be immune. Problem back after restart.
SDL2 init code looks that (w.o. error processing):
window = SDL_CreateWindow("Some label", SDL_WINDOWPOS_UNDEFINED,
SDL_WINDOWPOS_UNDEFINED, screenX, screenY, SDL_WINDOW_FULLSCREEN);
screen = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);
back = SDL_CreateTexture(screen, SDL_PIXELFORMAT_RGBA8888,
SDL_TEXTUREACCESS_TARGET, screenX, screenY);
SDL_SetRenderTarget(screen, back);
screenX and screenY are get in following way:
for (i = 0; i < SDL_GetNumVideoDisplays(); i++) {
for (j = 0; j < SDL_GetNumDisplayModes(i); j++) {
SDL_GetDisplayMode(i, j, &mode);
if ((mode.w * mode.h) > (screenX * screenY)) {
screenX = mode.w;
screenY = mode.h;
}
}
}
The crash can be reproduced sometimes.
