Description JKAbrams 2012-03-21 02:10:57 UTC

Palapeli uses large amounts of memory.
Some examples:
image: 16105 x 3198px 8 662 KiB, pieces: 819, memory: 2 273 304 KiB 
image: 7200 x 4050px 7 831 KiB, pieces: 1000, memory:  1 533 672 KiB 
image: 11232 x 7488px 4974 KiB, pieces: 2000, memory: >2,7 GiB (out of memory)

Reproducable: Always

Notes (if applicable):
-64 bit
-nVidia graphics driver 295.20
-I don't have a swap partition

Yes, Palapeli does not use graphics card acceleration at all. All pixmaps on the screen are pre-rendered at load-time and reside in memory. You can cut down on memory usage drastically by disabling the graphical effects (drop-down shadow and 3D bevels) in the configuration dialog. This should reduce memory usage by at least 50%.

The proper fix of course is to use OpenGL instead of simple pixmap-blitting. This is perhaps going to be feasible with Qt 5's SceneGraph framework. For the time being, you'll have to live with the aforementioned workaround.

Thank you for the bug report.

As this report hasn't seen any changes in 5 years or more, we ask if you can please confirm that the issue still persists.

If this bug is no longer persisting or relevant please change the status to resolved.

No longer a problem AFAIK, but PC memories are bigger nowadays.
