My projects use SDL/GPU drivers (Win10, C/C++, lvgl ver 8.3), it can work well generally. but when I let the machine sleep (my develop computer: Win10 system), and wake up again, the lines has drawn will disappear and can never draw and display the new lines. Whether has someone has the same problem? and how to resolve this bug?
NOTE: draw line call the function that named “lv_draw_sdl_draw_line”.
Only the lines disappear? Everything else is there?
thank you for reply. Only line disappear.
Could you try with this PR? feat(sdl_render): support all draw task types by kisvegabor · Pull Request #6437 · lvgl/lvgl · GitHub
Note that it’s for v9. Is it an option for you to move to v9?
sorry, we cannot update to v9.0, otherwise we cannot release our product as plan.
I would like to know whether you can reproduce this problem? and it helpful if you can
tell me the reason and solution to resolve in v8.3
Could you open a GitHub issue fir that and tag @mariotaku? He implemented the SDL renderer of V8 and hopefully he can take a look.
