@Karry , sorry I make mistake. Using Qimage instead QPixmap improves memory usage, and that doesn't impact the cpu usage. CPU usage increases when applying all commits of the PR...
The tile caches settings are already configured. On device mobile the offline tile cache size is 100MB. Reducing it has no effect on the OOM. The screen config reported by...
@Karry , I found the culprit.
The culprit is the up-scaling of tiles. In commit 07e27ba8d45bd6f0043b374e9abb5e6f633708ea `double finalDpi = mapDpi * 2 * this->screenPixelRatio;` Fixed/Updated by next commit d721e811da67839160e23c7af34e16d642ef4c64 ``` double finalDpi = mapDpi * this->screenPixelRatio;...
Also I suspect a bug in the Qt backend, some times the issue doesn't occur and memory keep under control, and some times it increases continuously like a leak or...

Well, it is fixed now with the PR #1647 . The root cause is the dpi is factorized 2 times by the screen pixel ratio on HiDPI. Thus causing an...
Some bad news. Trying with an older device with arch armv7 and Android 10. The app stills to be killed after few moves and offline tiles computing. At the moment,...
Now the root cause has been identified, I close this and will continue in the PR #1647.
@Karry, I captured tiles bold in the mobile when activating the tiled renderer: The Qt screen size is 360 x 768, and pixel ratio is 3.0 for this Xperia 10....
